PUREBURG FY3433 FY3432 Replacement Filter Compatible with Philips AC3256 AC3257 AC3259 Series 3000i Air Purifiers, Part Number FY3433/10 FY3432/10,H13 True HEPA and Activated Carbon Set

UpdateManufacturer 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.

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

I purchased this filter set for my Philips air purifier. The HEPA filter was perfect, fitted into place nice and snug and appeared to be of similar quality to the original Philips filters i normally purchased every 6 months. The activated carbon filter however was very different. To start with when i took the carbon filter out of the protective bag, the first thing i noticed was that the carbon pieces were not secured into their hexogen plastic holders. A large portion of the filter was empty due to the carbon having come loose. I tried to manoeuvrer the pieces back into the hexogen holes but it was a thankless task as there were so many of them. After spending around 30 minutes manipulating the individual pieces i gave up, i put the filter into my purifier only to find it was too small! It just kept falling out.I very rarely return things to amazon but this is one product i would have returned if i had not discarded the packaging. I didn't expect a filter not to work, hence why i opened and threw away the packaging upon delivery.I am afraid i can not recommend this filter set to others, you may be wise to pay more and buy another brand or stick with the Philips original filter set.I hope that you found my review helpful.

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.

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.

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.

Both filters have been made to fit exactly into my Philips AC3256 hepafilter, even more tightly than the originals. They are well made and the carbon one is well packed.

These do not fit the Philips air purifier as stated. Unfortunately did not try them straight away and missed the return date.
