– Replacement Filter Compatible with Philips AC3256 AC3257 AC3259, Series 3000i Air Purifiers, Part Number FY3433 FY3432, H13 True HEPA and Activated Carbon Set

Both filters fit perfectly in AC3256 contrary to reviews - it seems they have updated the size of the carbon filter to make it slightly bigger. 5/5

Update Manufacturer has made adjustments to size of carbon filter since last purchased. Perfect snug fit on both filters. Having had problems sourcing genuine AC3256/60 Philip filters (and at huge cost) decided to try this company out. They have a web site and I believe claims they make are accurate. The HEPA filter fitted perfectly, snug fit so no leakage of air. The carbon filter however, was 2-3mm too narrow width. Emailed company and replied that this is a problem they are aware of and will resize next production run. My machine usually lets me know once a year to replace these filters so should be sorted by then.

Not fit for purpose! Previous purchase did fit fine. But this time the foam outer strip was missing from the charcoal filter so it was too small to fit securely in the unit. With the charcoal filter not fitting snug, air leaks past this layer which is pretty useless for an air purification system.

I can confirm both filters are a very good, snug fit on the AC3259. I have previously only used the Philips replacements but these seem to be of the same build quality and a lot cheaper. We will see how they perform over time but so far very impressed.

Materials seem comparable to the genuine items. They don’t fit quite as well but as long as you’re careful during installation/removal they should work just fine.

A few people were concerned with the fit, but maybe I got lucky or they just updated the design as mine fit snugly.

It fits inside the Phillips 3000i air purifier but quality of filters is far from what original Phillips parts. Looking closely noticed the unit vibrates with new filter fitted just slightly. Can’t say how well it works yet. It’s a bit to expensive for what you get.

These replacement filters for our Philips air purifier are fractionally larger than the originals so fit more tightly (but they do fit) and now we have lovely pure air again.

Tutto come da descrizione non ho notato differenze dai filtri originali e ho risparmiato parecchio rispetto ai filtri originali

Brilliant product & exactly as advertised

Toujours très bien.

Super

Los filtros parecen estar bien hechos pero huelen fatal, incluso despues de mas de un mes de uso siguen impregnando la estancia con un desagradable olor: justo lo contrario a lo que deberian hacer. Merecia la pena probarlos por la diferencia de precio con los recambios originales, pero ha sido un fracaso.
