Blueair Genuine HEPASilent Replacement Filter for Blue 3410 Air Purifier – Removes up to 99.97% of Pollen, Dust, Pet Dander, Mould, Bacteria & Viruses Activated Carbon Reduces VOCs, Odours, Chemicals

I think the 3410 has been a great air purifier but it finally came time where the filter needed replaced. I think it advises changing every 6 months but I use mine fairly heavily and the original filter has lasted me far longer. I noticed there are a couple of cheaper options from other makers but when I checked the original filter and seen what it had collected after how long it lasted i was happy enough to just stick to the official one rather than take a chance to save a few quid. Very impressed.

quite expensive but it is a genuine replacement, it’s a filter, it does what it needs to do

Quite expensive but our old filter did last over two years. Easy to fit. We don't have our air purifier on all the time, so would expect this filter to last a long time until the red replacement light comes on again.

Genuine product very good price

If you are careful with a vacuum cleaner then you can make these last about twice as long as it says.

Exactly as described, no defects.

Genuine product and effective

Filter fitted as it should - all good
