Air filters
Easyboost EB497-525
Two foam filters with the widest cross-reference list here — and the only listing that states which neighbouring housing sizes it also fits.
What the maker prints on its own page
An air filter for lawnmowers and pedestrian tractors from two named engine
makers and twelve further machine brands, stated as perfectly suited to
replacing a clogged and worn filter. The foam from which the filter is made is
stated to have been carefully chosen for long life and optimal filtration.
Compatible with one engine maker’s six named engine families, with six original
part numbers listed. Also compatible with the other maker’s 3 to 5 PS and 3.5
to 6 PS engines, with sixteen model numbers and six original part numbers
listed. Also compatible with original references from six further brands, each
named with its number.
The filter measures 132 × 114 × 22 mm, and the maker states it also fits slots
of 133 × 114 × 20 mm and 130 × 112 × 20 mm.
The line nobody else writes
The filter measures 132 × 114 × 22 mm, but also fits slots of
133 × 114 × 20 mm and 130 × 112 × 20 mm.
That is the most useful line on this shelf.
Three filters here are within two millimetres of each other in outline and
differ in depth: 20, 22 and 25 mm. A buyer with a caliper and a housing has no
way of knowing whether a 2 mm difference matters.
Here it is answered, and the reason is the material: foam compresses. A
22 mm foam element will seat in a 20 mm slot and seal against the faces, where
a 25 mm paper one would stop the cover closing.
Stating which neighbouring sizes are covered turns a guess into a fact.
Foam, stated
The only listing on this shelf that names foam, and it settles the maintenance
question in the other direction from the paper elements here.
Foam washes: warm soapy water, squeezed rather than wrung out. Most engines
then want it lightly oiled with engine oil and squeezed to distribute it —
though this listing does not say so, and the engine’s own manual is where that
is decided.
Over-oiling is the mistake: a soaked element restricts the air as effectively
as a blocked one.
The cross-reference list
Eight brands’ original part numbers, sixteen engine model numbers, fourteen
machine brands.
That is the widest list on the shelf, and it is the correct way to sell a
commodity part whose only identity is the number stamped on the thing it
replaces.
This site prints every reference exactly as the seller gives it.
Two in a box
Like one other listing here, a pair. On a part replaced once a season that is
two years — and on a foam element that will be washed several times before it
is replaced, a spare in the shed is what lets you wash one and run the other
while it dries.

Beyond the euro zone, the British Amazon store prices it in its own currency, which the spread above sets aside.
Nothing came back from the American Amazon store at all; the buy button there runs a search rather than opening an empty page.
