Alen - BreatheSmart FLEX

I went with this one for my daughter’s bedroom - she has severe seasonal and animal allergies. It’s currently $249 instead of $349 to boot. https://alen.com/products/alen-breathesmart-flex-hepa-air-purifier

Do you have a budget to stick with? I’d look at something like an Alen breatheright flex in each room. They have a voc filter option that has extra carbon in it. However, Being that it’s a medical building is there already some kind of air exchange that could be adjusted? Have you talked with your facilities person? I may start there before going the purifier route.

Not a Dyson. Seriously. Alen, Coway or winix.

Dyson in general is not known for high quality especially for the price they charge. Also their customer service is shit. The other 3 I listed are much better options. You’ll want as much carbon in the filter as possible. Alen VOC for example.

+1 for Alen. With that size room, the Flex model is perfect. Then I’d grab the “odor” or “VOC/smoke” filter to deal with odors. Just note that the flex doesn’t come with any apps or ionization like the other commenter. That starts with the 45i and 75i models. Also are great but are way overkill for your room.

It doesn’t exist on the flex model. It’s purely mechanical filtration. Which is what you are looking for.

1) Ask r/airpurifiers 2) Alen is really the only true BIFL brand because they offer a lifetime warranty for as long as you buy genuine Alen filters. Plus the filters last a long time too and they are incredibly quiet. Coway and Winix are good too just not at the level Alen is. **Avoid Dyson, blueair and Levoit. They’re junk.** 3) As for sizing, this part is important: most manufacturers advertise crazy sqft numbers (1,000sqft+ for a tiny tabletop unit) just know that most of the time this is disclaimed by stating it can filter all the air in a 1ksqft room ONE TIME per hour. If you actually want to filter your air, industry standard is FOUR times per hour. So in reality, that 1ksqft unit is really only good for a 250sqft room **on full blast** which is usually loud. What kind of space are you trying to purify? An Alen 45i or 75i is great for living rooms and open spaces, then A flex or 25i bedrooms would work well.

Alen is the best. I got this deal. 2 in kitchen/living room and one in bedroom. Amazing for smell and pet allergies. Only downside is filters are $80-$100 but they last for around 6-9 months. I also buy extra filter covers to make them last longer. https://alen.com/products/buy-2-breathesmart-flex-get-the-3rd-free

I like Alen - they're filters aren't too expensive, they're quiet, and use a lot less electricity than other air purifiers I've seen. I've had this model for about 7 years now and no issues. [https://amzn.to/3H6Nhu8](https://amzn.to/3H6Nhu8)

I have a Pyr. I got an Alen BreathSmart Flex on sale for my living room and it's made a world of difference. I have 2 Coways for other rooms too. Night and day diference.

Just purchased a couple Alen Flex machines after loads of research. Didn't feel I needed all the bells and whistles that come with newer models. It is being phased out but uses the same filters as 45i, the lifetime warranty was a big plus.

Thanks for the feedback guys. I went with the Alen flex and got it on Amazon so it’ll be here asap. No weird filter issues, ionizing BS, etc. and it moves air well for a room my size

I bought a refurbished Alen Breathesmart Flex from the Alen website for about $100. Works fine so far. I thought I'd mention it since, if cost is a factor, you can't go too far wrong at that price.

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.

I bought the Alen BreatheSmart 9 years ago for $500 - a big investment. At the time I was desperate for allergy relief and it delivered. It's still going, no regerts.
