BLUEAIR Blue Pure 211+ Light Gray Pre-Filter, Washable Fabric Traps Pollen, Pet Hair & Dust, Lunar Rock

Works as advertised

I have 3 different colors of this pre-filter dust cover; dk gray, turquoise and this very light color. These covers are durable (they’ve lasted years with regular laundering in the washing machine, air dry only!) and retain their elastic fit very well as long as you don’t throw them in the dryer. The only caveat is for the light color: unless you are disciplined enough to wash it on a set schedule, be forewarned that unlike the darker colors - you cannot see the dust accumulation as a visual signal. Other than that, it’s well worth buying.

It is made for the unit and looks much better than the old cover.

First, I'm an avid fan of a famous review company, but we aren't allowed to say who that is... They rated this air purifier at the top of the list. I have two other air purifiers, an Electrolux which also does an excellent job, and an LG which is pretty good. But this one... It's really simple to use, and while it seems a little big, I noticed the difference overnight when my nose wasn't itchy and I wasn't coughing throughout the night. I have a whole house electrostatic hepa filter on my furnace also, but I keep the damper to my bedroom turned off. A cat and a dog, and three litter boxes contribute to the dust. But when I woke up the first morning after turning it on, and sunlight was coming in my room, you could barely see ANY dust floating in my bedroom. I wish they sold a true whole house version because it would be worth it for this big old farmhouse.

needed a replacement. works well and easy to wash.

This is a pricey air-purifier but it's well built and works great. I recently adopted a very, very smelly dog. Not just a dog that smells like a dog, this is a dog that has constant skin infections which smell like molding bread and fluctuance that can make your eyes water. Walking into the room where he's kept full time (300sqft), no longer like walking into an invisible wall of stench. The cloth outside filter keep his fur and dust from mucking up the filter so the filters last a long time. On the highest setting it sounds like a medium speed fan, but on it's lowest setting it is nearly silent. It sits right next to my bed and does not disturb my sleep, but the button light is always on. It is a soft glow and not a nuisance on the low level, but on the highest setting it is a little too bright for sleeping right next to.

It is exactly what you expect it to be and nothing more. it doesn't need to be flashy to be effective.

My place is very dusty and using these covers helps the filter to last longer. I have the darker blue, dark grey and silver. The silver color is my favorite and it makes it so the filter does not stand out as much.
