Good price , great produce

As described. It works extremely well. That said, I bought the same product prior for my daughter, when she complained about dust in her student accommodation, during her 1st year at University. I therefore bought the same for my own home. It does get rid of pet and smoke smells. Equally Amazon had the best sale price.

Great price! Thank you. Great product!! It’s all working much better with new filters!..

Yes haven't used it yet but I know it will do the job have another month b4 it's due to be replaced the old 1

Does the job.

I didn’t think the air filter was doing much until I came to change it - it was absolutely caked in dust which begs the question where would the dust have otherwise gone? Totally worth the money!!!

Blueair replacement filter was very easy to replace. The instructions from the original purchase gave easy to understand instructions. It took approximately 10 minutes.

The size that was mentioned in the description is not correct. At all. This filter is smaller by 25% from original size
