We also have four Blueair headphones… 3x 5210i and 1x 5410i. The filter performance is excellent, but the support is abysmal. We noticed a bearing failure in one of them after 3 months, and support kept going back and forth, explaining that they couldn't hear the problem in a multitude of videos. Interestingly, half a dozen people we know heard the problem instantly. 😉 Product great. Service terrible.

I have two Blueair DustMagnet 5440i. There is an extension to connect it to HA with all sensors and controls available. It filters air great, so my wife can survive the allergy seasons. Additionally, it filters air from nasty smells, like ones my son carries after extensive sports training.

I’ve got a bunch of Blueair filters including the dust magnet one and I love them. They will sometimes have great sales, which is how I ended up with my first two during Covid. I recently also got their humidifier which is amazing. My mom came to visit and said she was sleeping better than she had in a while because her allergies were finally more settled down, which may have also just been from a change in habitat, but I really think these air purifiers are great.

Even their dust magnet has a shelf on top and exhausts on the sides

My Blueair dustmagnet has the top and bottom as intakes, exhausts in the sides. The top has a shelf that you can actually use as a shelf. I think something like that would help

I also have a couple of BlueAir and the scheduling feature for smart purifiers is very nice to have. I have it set to run on the lowest fan setting all the time which is so quiet it's undetectable, and ramp it up for a few hours in the afternoon right before we get home from work.

Multi level approach works well. - Decent filter you change more regularly for your HVAC (agree with others that MERV shouldn't be too high) - Clean floors, if you have carpet get a deep carpet cleaning annually - Room air filters. I've had luck with Blue Air. Have one jig one for living room and some small ones for the bedrooms. - Have you tried using regular saline rinses for your nose? I use the powder saline mixes with the plastic applicator from NeilMed, but there are others out there. While my allergies are pretty mild, I haven't needed to take any allergy medicine at all since using these.
