Vervangend Luchtfilterpapier HUISDIER Universeel HEPA-filtermateriaal Stoppen van Allergeenstof Pollen Accessoires voor Thuiszuivering

Seems pretty decent. Seems to be filtering out cooking stove fine dust well enough

Works very well cut up into 3 lengths. Width is perfect. For £7 = 2.33 per HRV that is a huge saving over the branded Mitchusbshi at £64! Bargain.; But note they are not tethered with cotton cord like some other generic ones., but seems to hold position inthe frame of the ventilation. Baragin Give they go black in the London Smog!

Es un papel, no un filtro hepa

Also der Luftfilter is sehr klein ohne Verstärkte Ramen sie die meisten also ich wurde von einem Kauf abraten

30cm x 5.5cm x 13mmPourquoi ne pas afficher clairement les dimensions ?Il est emballé "compressé" vous devrez étirer le filtre.. il ne tiendra jamais en place, il ne gardera jamais une taille étendue.

TLDR: Item is about an A4 size paper without pulling or folding, can get bigger if you stretch it out, maybe about double the size.Item is exactly as listed, 1 piece of filter paper. I am not filter paper expert, but it does feel like one hepa filter.The problem I think most people will have with this listing, is there is no size guide, only weight, so one may not be sure if this is what they need or if this is enough.To help those people, the whole item is about an A4 sized paper give or take a little, and you can stretch it out to lay flat at about double that size, but it would probably decrease the effectiveness of the hepa filter.item comes in a sealed bag, which is great, you know it is new and not contaminated on arrival.the deduction of 1 star is purely because of the listing being unclear about how large the surface area of the filter is. hopefully this won't be an issue for others now.
