The best pond filter mats, compared.
Top pick: Eight-layer filter pad 60 × 40 × 1.5 cm – Tied on 80 with the Borlech sheet; 4.8 from 199 reviews is the higher amazon rating, so this pad is the top pick. Best value: Borlech 20 PPI foam 47 × 47 × 2 cm – Highest price-against-the-sheet block in the set, at 15, for a stated 20 PPI sheet at about £7.99 with 4.5 from 314 reviews. Updated October 2026.
A pond filter mat is the foam sheet, polyester fleece, wool roll or pre-cut pad that sits in a pond or aquarium filter and strains solids. Open-cell foam also gives bacteria a surface, so it is both a screen and part of the biological stage. Wool and white floss are mainly a fine polish, and they clog sooner. Clearer water in a review is not a measurement of ammonia or nitrite. Grade, size and format are set out in the [pond filter mats buying guide](/hub/garden-ponds/pond-filter-mats/sub/pond-filter-mats-buying-guide). You judge a listing by the job, the stated size and thickness, whether or a colour grade is given, and whether UK reviews describe crumbling, a vacuum pack that stays flat, or holes that miss the tray. Finer foam, white floss or wool belongs later. A shaped spare must name the exact model, including a plus version. Measure the chamber, the thickness, and any centre hole or tray cut-out. A pre-cut set that misses the baskets is the wrong part.

Personal buying guide
Question 1 of 2
Will you cut the mat, or must it match a named filter?
This multi-layer pad is 60 × 40 × 1.5 cm at about £8.99, and a bullet lists eight layers from honeycomb mesh through fibre to biochemical cotton. The star line is 4.8 from 199 reviews, which is the highest star line in this set. Most saved texts praise reuse and clear tanks, while one says a polish clogged in about two and a half days. A bullet names small ponds, tanks, turtle habitats, garden and hydroponics, and you can cut the pad. An outdoor-pond question is on the page and is not answered as its own line. PPI is not stated, and there is no named filter model. It is the top pick when you want a layered cut-to-fit pad with a large review file and you will change a polish that clogs within a few days.
Pros
Cons
Best for: You want a layered pad for a small pond or tank and you can cut 60 × 40 cm to the chamber.
Less suitable: You need a single stated PPI, or a shaped spare for a named All Pond Solutions or SunSun model.
Specifications
Common questions
Does the listing mention an outdoor pond?
A bullet says small ponds, tanks, turtle habitats, garden and hydroponics. A question asks about outdoor ponds and is not answered as its own line.
What is the layer claim?
The bullet lists eight layers: honeycomb mesh, hydrophobic fibre, tight mesh, and biochemical cottons.
What complaint is in the saved reviews?
The star line is 4.8 from 199. Most saved texts praise reuse and clear tanks. One says a polish clogged in about two and a half days.
This 5 m roll of pond filter wool is listed at 10–12 mm and about £17.99, and the title names pond and koi. The star line is 4.5 from 441 reviews, the largest count in the set. Saved UK texts praise cutting and clearer ponds, and also call the wool thin, fluffy, liable to split, or prone to shed fibres. The only saved bullet claims the wool removes all fines, which is a listing line rather than a measured result. No brand appears in the raw title. The manufacturer reference is dv119, and the roll weighs 360 g. Material, outdoor use and maintenance are questions on the page without answers. It is the long wool file here if a coarse stage is already in the filter and you can accept fluff and shedding.
Pros
Cons
Best for: You already have a coarse stage and want a 5 m wool roll with a long review file.
Less suitable: You need inlet foam, a named brand, or wool that reviews do not describe as thin.
Specifications
Common questions
Does the saved listing name a brand?
No. The title is a description. The manufacturer reference is dv119.
What does the only saved bullet claim?
It says the wool removes all fines from the water. Material, outdoor use and maintenance are questions without answers.
What do the saved UK reviews argue about?
The star line is 4.5 from 441. Texts praise cutting and clearer ponds, and also call the wool thin, fluffy, liable to split, or prone to shed fibres.
The Borlech sheet is a stated 20 PPI foam, 47 × 47 cm and 2 cm thick, at about £7.99. The star line is 4.5 from 314 reviews, the longest file among the foam sheets in this set. The bullets say you can cut it and clean it for reuse, and the title names ponds. Saved texts include warm water to expand a compressed sheet, and two reports that the foam crumbled into black pieces. At 80 g it is a light sheet, so a deep chamber can still look underfilled after you cut it. There is no named filter model and no salt-water line. It is the best value here when you want one checkable 20 PPI grade and you will send back a sheet that falls apart.
Pros
Cons
Best for: You can measure a chamber and cut a 20 PPI sheet, and you will return a sheet that falls apart.
Less suitable: You need a pre-cut spare with centre holes, or a polish wool roll.
Specifications
Common questions
What grade is printed for this sheet?
20 PPI, 47 × 47 × 2 cm, one pack.
Does the listing say it can be reused?
Yes. The bullets say it can be cleaned and reused. The page also asks that question and does not answer it separately.
What failure shows up in the saved reviews?
The star line is 4.5 from 314. Saved texts include warm water to expand a compressed sheet, and two reports that the foam crumbled into black pieces.
INGVIEE packs six white floss pads and three blue coarse foams at about £16.99, titled for the All Pond Solutions 1000EF+. The bullet says the set is custom-made for that external filter. The star line is 4.5 from 129 reviews. Several saved texts say the pads fit a 1000EF or 1000EF filter, and one says the holes do not line up with a 1000EF. Reviewers say the white floss gets dirtier and is replaced sooner than the blue coarse foam. The pack weighs 70 g and the material is not stated. It is the shaped set to consider for a 1000EF+ once you have checked the holes, not an automatic match for a 1000EF without the plus.
Pros
Cons
Best for: Your cabinet says 1000EF+ and you will check the holes before you run the pump.
Less suitable: A 1000EF without the plus, a 1400EF, or a filter you will fill with a cut sheet.
Specifications
Common questions
Which model is on the title?
All Pond Solutions 1000EF+. The bullet says the set is custom-made for that external filter.
Do the saved reviews agree on fit?
Several say the pads fit a 1000EF or 1000EF filter. One says the holes do not line up with a 1000EF. The title’s plus suffix is the difference to check.
Which pad do reviewers replace first?
Saved texts say the white floss gets dirtier and is replaced sooner than the blue coarse foam. The star line is 4.5 from 129.
INGVIEE packs six white floss pads and three blue coarse foams at about £13.99 for the All Pond Solutions 1400EF and 1400EF+. The star line is 4.5 from 32 reviews. Three saved UK texts say the pads do the job and do not describe a fit failure. The bullet calls it an INGVIEE replacement designed to work the same, not a genuine All Pond Solutions pack. Material and thickness are not stated, the pack weighs 101 g, and a wash question on the listing is unanswered. Buy it when the cabinet says 1400EF or 1400EF+, and leave it if the model is a 1000.
Pros
Cons
Best for: Your filter is an All Pond Solutions 1400EF or 1400EF+ and you want white floss plus blue coarse pads.
Less suitable: A 1000EF, a 1000EF+, or a housing you will fill by cutting a sheet.
Specifications
Common questions
Which filters does the title name?
All Pond Solutions 1400EF and 1400EF+.
Is this the manufacturer’s own part?
The bullet says it is an INGVIEE replacement designed to work the same. It does not say it is a genuine All Pond Solutions pack.
What do the saved reviews cover?
The star line is 4.5 from 32. Three UK texts are saved. They say the pads do the job. They do not describe a fit failure.
The size line on this polyurethane foam says 35 PPI and 47 × 47 × 4 cm at about £8.09. The bullets also offer 2 cm and 4 cm, and 20, 35 or 50 PPI, so the page prints more than one grade. The star line is 4.3 from 68 reviews. Saved texts say a soak restores size, including to 4 cm, and one says the sheet was an uneven offcut. The listing tells you to use warm water to restore a compressed sheet and claims repeated washing. It weighs 330 g, and the page also asks about a laptop bag, which the sponge text does not answer. Cut it for a pond chamber only after you know which PPI and thickness the seller will send.
Pros
Cons
Best for: You can confirm the PPI and thickness with the seller before you cut the sheet into a pond chamber.
Less suitable: You need one grade printed once, or a shaped spare for a named model.
Specifications
Common questions
Which grade should you treat as the item in the box?
The technical size line says 35 PPI and 47 × 47 × 4 cm. The bullets also offer 2 cm and 4 cm and 20, 35 or 50 PPI.
Why are there questions about a laptop bag?
The page asks about a 15.6 inch laptop, a shoulder strap and waterproofing. The product text is a filter sponge. Those questions are not answered.
What do the saved reviews say about thickness?
The star line is 4.3 from 68. Texts say a soak restores size, including to 4 cm, and one says the sheet was an uneven offcut.
INGVIEE pairs one yellow fine sponge with one blue coarse sponge at about £14.49. The title lists SunSun CBF-350, CBF-350B, CBF-350C, CBF-550 and CBF-200T, while a bullet says the pair fits the CBF-200T. The star line is 4.3 from 63 reviews. Seven saved UK texts are short. They mention easy cleaning, a clean pond and a fit, and none describes a failed model. Material and thickness are not stated, the pack weighs 150 g, and a wash question is unanswered. The CBF-200T is the fit the bullet actually states, so check the other four models on the title before you rely on them.
Pros
Cons
Best for: Your filter is a SunSun CBF-200T, or you have checked the pair against one of the other models on the title.
Less suitable: An All Pond Solutions EF filter, or a CBF model that is not on the title.
Specifications
Common questions
Which SunSun models are on the title?
CBF-350, CBF-350B, CBF-350C, CBF-550 and CBF-200T.
Why is the fit narrower in one bullet?
A bullet says the yellow and blue pair fits the CBF-200T. That is a smaller list than the title.
What do the saved reviews say?
The star line is 4.3 from 63. Seven UK texts are short. They mention easy cleaning, a clean pond and a fit. None describes a failed model.
This white polyester fleece is a 5 m by 69 cm roll at about £15.99, with 12–15 mm claimed once it has expanded. The listing says a vacuum pack should reach that thickness in 48 to 72 hours, and the bullets say scissors will cut it. The star line is 4.3 from only eight reviews. Saved texts mention cutting for tanks and a pond, and one reviewer says the piece looked about 2 m rather than 5 m. It weighs 580 g and the bullets name freshwater and saltwater. A replace interval is asked on the page and not answered. Treat it as a wide polish roll only after you measure the length on the floor.
Pros
Cons
Best for: You want a wide fleece roll to cut for pond or aquarium polish, and you will check the length after it expands.
Less suitable: You need a stated PPI foam, or a review file large enough to judge shedding.
Specifications
Common questions
How thick is the roll once it has expanded?
The listing says 12–15 mm, and that a vacuum pack should reach that thickness in 48 to 72 hours.
Can it be cut?
Yes. The bullets say scissors and any size. The same question is asked on the page and not answered as a separate line.
How many reviews are on the listing line?
4.3 from 8. Saved texts mention cutting for tanks and a pond, and one reviewer disputes the 5 m length.
The white polyester pad is an 8 × 100 cm three-layer sheet at about £6.19, and the bullets say you can cut it to another size. Across 187 amazon.co.uk reviews the line is 4.1. Saved UK texts say it needs fluffing after a vacuum pack, and that it can be smaller than expected or clog quickly. The bullets name freshwater or saltwater aquariums, while the title also says pond, so you still match it to the housing you are filling. A specific-uses field says Weaning, which does not describe a pond mat. At 40 g the pad is a light fibre sheet, and thickness is not stated. It suits a cheap cut-to-size polish if you measure it after it expands and you can accept a fast clog.
Pros
Cons
Best for: You want a cheap white fibre pad to cut for a small tank or pond polish, and you will measure it after it expands.
Less suitable: You need a stated PPI foam sheet, or a pad whose size you can trust before you open the bag.
Specifications
Common questions
Does the listing say you can cut this pad?
Yes. The bullets say it can be cut to another size.
Is salt water mentioned?
The bullets say freshwater or saltwater aquariums. A question on the page asks the same thing and is not answered separately.
What do the saved reviews say about size?
The listing line is 4.1 from 187. Saved UK texts say it needs fluffing after a vacuum pack, and that it can be smaller than expected or clog quickly.
This unbranded black sheet is listed as 20 PPI at 50 × 50 × 2 cm for about £7.99, the same price as the Borlech 20 PPI sheet. The star line is 3.6 from 19 reviews. The title and a bullet name freshwater, saltwater, reef, sumps, pond filters and canisters, and the bullets say you can cut it and rinse it during maintenance. Two UK texts are saved: one says quality, and one says the vacuum pack is poor quality. There is no model number, and the sheet weighs 120 g. It is a second 20 PPI option only if a sample of 19 reviews is enough for the chamber you are filling.
Pros
Cons
Best for: You want a 50 cm square 20 PPI sheet and a sample of 19 reviews is enough for you.
Less suitable: You want the longer 20 PPI review file, or a shaped spare for a named filter.
Specifications
Common questions
Does the listing mention salt water?
Yes. The title and a bullet name freshwater, saltwater, reef, sumps, pond filters and canisters.
Is a model number given?
No. The technical block has package size and weight only.
What is in the saved review file?
The star line is 3.6 from 19. Two UK texts are saved: one says quality, and one says the vacuum pack is poor quality.
This white sheet is listed as 100 × 40 × 2 cm at about £8.59, and a bullet says you can cut it and rinse it gently in water from the original tank. The title says pond, while the specific-uses field says Indoor. No customer-review line is in the file, so the score is 0. Salt water is only a question, PPI is not stated, and no replace interval is given. The material line says biochemical filter cotton, and the item weighs 240 g. It is a cuttable fibre sheet if that indoor-uses field still matches the housing you are filling.
Pros
Cons
Best for: You want a 2 cm fibre sheet to cut, and you accept a listing with no reviews.
Less suitable: You need a star line, a stated PPI, or a pad the listing clearly describes for an outdoor pond.
Specifications
Common questions
Can the listing be read as a pond mat?
The title says pond. The specific-uses field says Indoor. Salt water is only a question.
How does the bullet say to clean it?
Rinse gently in water from the original tank. No interval is given.
Is there a star rating?
No customer-review line is in the saved listing, so the score is 0.
This white floss sheet is listed at 100 × 60 cm for about £10.99, with a 50-micron claim in a bullet and a note that you can cut it. A bullet says the thickness is 3 cm, while the product-dimensions line says 0.3 cm. No customer-review line is saved, so there is no star rating to lean on and the score is 0. Landscape ponds are named in a bullet, and the polymer is not named. The replace interval is a question on the page without an answer, and the sheet weighs 282 g. Do not read the 50-micron line as a PPI, and do not order it until you know which thickness is in the parcel.
Pros
Cons
Best for: You already understand the thickness clash and still want a large cuttable floss sheet.
Less suitable: You need reviews, a stated PPI, or one thickness you can trust on the page.
Specifications
Common questions
How thick is this sheet?
A bullet says 3 cm. The product-dimensions line says 0.3 cm. Both figures are in the saved listing.
Does the listing answer how often to replace it?
No. That question is on the page without an answer.
Is there a star rating in the saved listing?
No customer-review line is saved, so the rating is not stated and the score is 0.
Twelve amazon.co.uk listings were scored out of 100 from the stored pages and the UK review notes already on file. Snapshot date 21 October 2026. Prices are in GBP. This is not a laboratory test. Clearer water in a review is not a measurement of ammonia or nitrite. A listing with no Customer Reviews line scores 0. If two scores tie, the higher amazon rating is the top pick, once. The highest price-against-the-sheet block that is not the top pick is best value, once. The weights below sum to 100. Deductions of up to 10 points sit outside those weights.
Amazon stars
40%The amazon.co.uk star line, as (rating ÷ 5) × 40, rounded. If the review count is under 20, that result is multiplied by 0.4 and rounded. If there is no rating line, the block is 0 and the whole score is 0.
Review depth
25%0 if there is no rating line, 8 if there are 1–19 reviews, 16 if 20–199, 21 if 200–999, and 25 if there are 1,000 or more. A thin sample cannot outrank a large one on stars alone.
Grade and fit you can check
20%Points for a stated size, a thickness or a named layer count, one grade (a single PPI, or blue and white labelled for one filter model), a pond or a named model in the title, and cut-to-fit or shaped holes. Points stay low when the page prints more than one PPI or two thicknesses.
Price against the sheet
15%Higher when a checkable grade sits at a lower price with a usable review sample. A shaped spare is not punished for costing more than a plain sheet if the holes are the point of the purchase. A roll with a handful of reviews does not take this block from a sheet with hundreds.
Buy the job before you buy the star line. A coarse sheet, a polish roll and a shaped spare for one filter model are not one list. Prices below are amazon.co.uk shelf prices in this set of twelve. This is not a laboratory test.
A pond filter mat is the foam sheet, polyester fleece, wool roll or pre-cut pad set that sits in a pond or aquarium filter and strains solids from the water. On amazon.co.uk you buy either a cut-to-fit sheet or a shaped spare for a named unit such as an All Pond Solutions EF or a SunSun CBF. Open-cell foam also gives bacteria a surface, so it is both a screen and part of the biological stage. Wool and white floss are mainly a fine polish, and they clog sooner.
Coarse open foam belongs at the inlet. White floss and wool are a later polish and clog sooner. A fine pad in the first basket chokes flow before the coarse stage has done its job.
Several sheets arrive compressed. The 5 m fleece listing says 12–15 mm after 48 to 72 hours, and one review disputes the 5 m length. Measure the sheet on the floor before you cut it to the chamber.
The plus suffix changes the holes. One saved review of the 1000EF+ set says the holes miss a 1000EF. Hosing every foam on the same afternoon also strips the biological stage. Rinse in pond water, and not all of it on the same day.
The first check is the job inside the filter. Coarse open foam belongs at the inlet. Finer foam, white floss or wool belongs later, as a polish, and it clogs sooner. A shaped spare has to name the exact model, including a plus version. The INGVIEE 1000EF+ set is not an automatic match for a 1000EF, and one saved review says the holes miss a 1000EF. The 1400EF pack names 1400EF and 1400EF+. It is a compatible set, not a genuine All Pond Solutions part. PPI means pores per inch.
Reticulated polyurethane is the usual pond sheet. Polyester fibre is the usual wool or multi-layer pad. Vacuum packs often need warm water, or 48 to 72 hours on the 5 m fleece listing, before they reach the stated thickness. Do not trust the packed photo. A kitchen sponge is not filter foam. Foam that houses bacteria should be rinsed in pond water, not under the tap. UK tap water is chlorinated, and PondXpert also names chloramine.
Three typical situations, each with a recommendation from this comparison.
Wildlife ponds need coarse media that will not choke a modest pump. The Borlech sheet is a stated 20 PPI foam, 47 × 47 × 2 cm, at about £7.99, with 4.5 from 314 reviews. The bullets say you can cut it. Two saved reviews say the foam crumbled into black pieces, so check it before you fit it.
Koi ponds need graded foam, with polish only after the coarse stage. This 5 m wool roll is titled for pond and koi, at 10–12 mm and about £17.99, with 4.5 from 441 reviews. Saved reviews also call it thin, fluffy, liable to split, or prone to shed fibres. It is not the inlet foam.
Aquarium owners often cut the same sheets, and a pond rank does not mean the pad fits their tray. The eight-layer pad is 60 × 40 × 1.5 cm at about £8.99, with 4.8 from 199 reviews, and the listing says you can cut it. PPI is not stated. Measure the chamber after you open the pack.
The top pick is the eight-layer filter pad, 60 × 40 × 1.5 cm, at about £8.99. It ties the Borlech sheet on 80, and 4.8 from 199 reviews is higher than 4.5 from 314, so the pad takes the award. One saved review says a polish clogged in about two and a half days. The best value is the Borlech 20 PPI sheet, 47 × 47 × 2 cm, at about £7.99. Its price block is 15, the highest in this set, with 4.5 from 314 reviews and two reports that the foam crumbled. Shaped INGVIEE sets are for a named 1400EF, 1000EF+ or SunSun CBF, and they are compatible packs, not genuine branded parts. None of these scores is a laboratory test.
Eight-layer filter pad 60 × 40 × 1.5 cm
Tied on 80 with the Borlech sheet; 4.8 from 199 reviews is the higher amazon rating, so this pad is the top pick.
Borlech 20 PPI foam 47 × 47 × 2 cm
Highest price-against-the-sheet block in the set, at 15, for a stated 20 PPI sheet at about £7.99 with 4.5 from 314 reviews.
