Every 6 months I replace filters in a room air purifier: blu air

Works great

They are super!!!Right size!Great price for 2 filters!!I’m a subscriber now….

I was skeptical about the quality of these filters which are half the price of the original Blueair filters. Upon inspection, they seem to be very comparable to the original filter in construction and fit. I don't know about the HEPA specs being accurate, but I will buy these in the future.

Fit perfectly into my 200 series blueair purifier. I was buying blueair brand filters through Costco, who stopped carrying this size. So far so good at a much lower price point.

The manufacturer's version of this filter is at least twice the cost. This filter fits perfectly and works great. It's a good value for the money.

I missed that these were NOT original BlueAir and are a knock off from China. No way to know the charcoal component is legit. My bad for not reading the description more carefully. I am cancelling my subscription.

Made to look like a blueair dual protection filter, even says that they are 2lbs each like the blue air product, are half the weight and use a much less effective carbon wool sheet instead of the 2lbs of the more effective activated charcoal pellets in actual and other off brand blueair replacement filters.
