Philips PureProtect Pro Série 4200 AC4220/12

This was recommended by Choice magazine. This is also my 3rd phillips air purifier. Note there are two filters in this model. Quieter than.both my other models yet effective in clearing rhe dust in my room. Versatile to use in bedroom or larger living space.

I don't wake up congested. The product is fantastic.

It has a sleep mode to give you ultra quiet operation. In its compact size it has a double fan design air purifier. I am able to now sleep without coughing. Thankyou

I've been using the Philips 4200i Series Air Purifier in the bedroom at night and now I wake up without a blocked nose. I didn't even realise it was a thing that could be fixed, I just thought it was one of those things you need to put up with! A true game changer, I highly recommend this product.

Does the job quite well,personally feel like filters could be more better compared to the price, As i owed few philiphs 1000i,i feel like filters quality is kind of same. They still both do a good job cleaning the air. Kids sleeps pretty well since i bought these units.
