Reusable cost effective air purifier
I have a dog and live in an area with high pollen - I've had these for 3 years and replaced the bulbs periodically. In my house my allergies are not an issue. I have 3 of these in the areas of the house that are most occupied - living room and bedrooms - The noise doesn't stop me from sleeping - it's white noise - I knew there was an issue when one of them started making louder noises. I replaced the bulb and the noise was gone. These IMO are effective - I also have one at work. I brought these from my town home that had smaller rooms - I'm now in a house with bigger rooms - still seems to work well. My mother bought these to reduce the smell of perm in her shop. It minimizes it.
