Genuine Filter for Blue Pure 411i Max and 411a Max Air Purifiers

This air filter is anazing. This 411 size is large and powerful enough to clea the air in a combined living-dining and kitchen….probably about 500 sq.feet. Even after a year I am surprised when I hear it rev up, even before I realize the need, when I am stir frying something and the steam and aromas start filling the air. I have a smaller one in my bedroom which works equally as well. I bought the filter to have ready but the signal has not yet been given to change. It is almost one year of constant use.

We use ours at the entrance to our kitchen . It’s on standby mode most of the time , it reacts to the slightest change in air quality , such as cooking with butter or slightly burnt toast etc . The indicator light will change from blue colour to orange for instance , and the fan speed will go to high speed and remove the contaminant !

Easy to use

I couldn’t be happier with the BlueAir Air Filter Filters! These filters have truly made a difference in the air quality of my home. The installation is a breeze, and they fit perfectly into my air purifier. Since I started using them, I’ve noticed a significant improvement in the air – it feels fresher, and there's less dust and allergens floating around. What I love most is how effective they are at capturing even the tiniest particles, like pollen and pet dander, which is a game-changer for anyone with allergies. The filters are also long-lasting, which means I don’t have to worry about changing them too often. These filters work quietly in the background, ensuring clean air without any noticeable noise. Overall, I highly recommend these air filter filters to anyone looking to improve their indoor air quality. They’re a reliable and cost-effective solution for a healthier, more comfortable living space!

Perfect fit and perfect replacement. Good product!
