Great for allergy symptoms

I have allergies all year and since I started using the Blue Pure air filter I have noticed a huge difference. My sneezing “attacks” have almost completely stopped and I definitely don't have the allergy symptoms as bad anymore. When I open my windows and shut my Blue Pure off, my allergy symptoms come back.

Grateful for this!

We have 5 air filters in our house. We had ours running before, during, and 3 days after the recent fires in Los Angeles (until the power was cut). We got power back a few weeks later and turned them on again. We are still in an evacuation zone. Our house is still standing but had almost no smoke. Thank you BlueAir!
