Active Carbon filter

Good filter and a tip is to lightly vacuum off the dust that collects on the outer surface (the surface facing outwards and not the surface facing the white hepa filter). Doing this ensures that more air can come into contact with the carbon. Note: the Air Purifier 2000 series can use both the FY2420/20 and FY2420/30 filters. The only difference is the /30 can go into the 3000 series and is generally more expensive or hardly offered at a discount.

Carbon media is a highly efficient method of air filtration. It does not last long because its properties is consumed, however its efficiency totally worth if you want a purified air inside your home. IT DOES NOT REMOVE DUST! IT FILTERS THE AIR! YOUR HOME NEEDS TO BE CLEANED/VACCUMED REGULARLY.

People giving less than 3 stars for price are cretins. The product works fantastic and you can taste the quality in the air, my sons asthma is easily managed at night with this filter. Of course it won’t last long if the air is bad quality, it’s doing what it’s supposed to do! It’s a FILTER not a VACUUM! Highly recommend.

These do what they are meant to. I am blown away by some reviewers mentioning dust on the filters. Please note that these machines are meant to clean the air- not vacuum. We switch the machines off EVERY WEEK and clean the filters. We also vacuum the rooms twice a week. The result? Hardly any dirt or dust on the filters, despite having two, very moulting cats. Please don't buy these to replace your vacuum cleaner. I can honestly say that the filters are well worth paying for if you value your health. You can taste the clean air and my wifes asthma has improved ten fold! The amazing thing is, when the cats use their litter tray, the machines comes alive, whiring into action, cleaning the air. Amazing sensors, Amazing Technology!

Great idea to get one wonderful investment Before I get this one I had terrible sinus infections I never thought that this cause by falling and germs or bacteria in my house. After spending lots of money and Dr. visit using nasal spray nothing work. I bought Phillips air purifier model 2889 and the first night are used it I slept like a log or like a mummy I woke up all my complaints from from sinuses disappeared. It works like a magic

Also keeps the humidity way up if you clean it weekly.

Good product, easy to install works well, easy to order online

The filter doesn't last long, accordingto the Phillips app it uses up 1% per day so it would only last 100 days. Same experience as others in here.

I purchased a new one in February 2020 and now in May I need a new one, the filter is already completely clogged up with dust. I do live on the 5th floor so I am not exactly right next to the street and not a main road either...
