I’m super happy with my Blueair 121 air filter it’s been great for allergies and a savior during the Northern California fires. I purchased the replacement filter now because I’m at the end of 5th month and expect to change it next month. Yellow change color hasn’t shown yet but will change it next month even if it doesn’t. Can’t review what it’s like to change but it looks easy.

I have had a Blue Air for just over a year and just recently chose to upgrade to the particle filter w/Carbon filter. I had been using the one that came with the initial purchase. It worked great, I just wanted to try this other filter. We live in Mt, and our house has a wood stove as our heat source, so during winter the stove is always going. We also have 4pets, so we bought the Blue Air to help with dust, dirt, and pet hair. The upgrade to the higher filter had a noticeable change for our household as we run it 24/7. There are less particles and dust in our house.

I have had Blueair filters in my residence for years. I currently have three (one 121 and two 411's) going 24/7. Here in Oregon we have forest fires every summer now. The smoke from the fires would make life miserable without the filters with smoke filtering capabilities. I replace the filters about every 9 months. I'd tell you how long the fan units last except I've never had to replace one. I'm very satisfied with the Blueair replacement filters and the Blueair units. The price is a bit high and I would prefer if the filters said made in the USA on them, but they get 5 stars anyway.
