Alen - BreatheSmart 35i

Longtime allergy sufferer. Alen air purifiers are the gold standard. Choose the BreatheSmart model that is one level ABOVE whatever your room's square footage is, and chose any filter designed for allergens or wildfire smoke. Keep the fan on the thermostat running (with or without A/C) and buy the best filter for your HVAC.

Not smart but I have two Alens and absolutely love them. I've had an older Breathsmart for 6-7 years and still works great. Recently bought a smaller one for my gym/mancave and it's also great. Won't look for another brand if I needed another one.

We have an Alen HEPA that we’ve owned for over 7 years. A couple of filter changes but still running like new.

I have an Alen BreatheSmart in each big room and an Alen T500 in the smaller rooms. They are basically silent and work amazingly. Plus you can get set up for filter deliveries every 6 months or so.

Alen air purifiers are the best I’ve ever tried. Get the latest models that are WiFi enabled and automatically adjust to the current level of impurities in the air. And change your filters regularly. Expensive but worth it. Mage a world of difference for my pollen allergies and living in desert dust.

We have an Alen breatheSmart. I like it. It’s sensitive to changes. It reacts as soon as we light a candle or cook. We change the filter once a year.

I love mine too

As a fellow teacher, I understand this so much. I was in the exact same boat with dust and outdated HVAC in my classroom. When I was shopping around, I actually reached out to parents for small donations to help cover the cost — most were super willing to chip in, especially since everyone’s so germ-conscious these days. I used [this Redditor’s air purifier database](https://www.reddit.com/user/mammoth_digger56/comments/1k1t9o8/air_purifier_brands_compared/) to compare specs. I ended up buying an Alen 35i… It’s not cheap, but it’s been a game changer. I actually bought a second one for my home after seeing how well it worked. Might be worth checking out if you’re looking for something that can really handle the space.

Just got a 35i for the bedroom and love how quiet it is. Strongly recommend.
