605

I have the Blueair 211 and Classic 605. Both are great air purifiers and make great noise on high, but they appear to be older models, so may not be easy to find. If you end up buying an air purifier that is too quiet, consider also getting LectroFan Classic White Noise Machine. It has lots of fan sound choices and is the only sound machine I have ever used that is loud enough for me.

BlueAir. I have both the ones that use fabric as a pre-filter, and the old classic Model 600 ones that were on sale hundreds off. Check their website for sales. With the fabric ones, you simply slip off the fabric and wash in the washing machine.

The BlueAir Classics have plastic tops and the flip up control panels are plastic…of and so are the panels themselves at least. Nice units though.

My experience is with the Blueair Classic 605 model. Not sure if that is before or after the 400.

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.

Blueair has a small one that would fit that space for $99 on Amzn or other retailers. I have next size up and so far so good and noticeable decrease in dust. I like being able to control it and monitor its cleaning via the app. Not advocating for the company other than after doing some research I settled on them and so far am happy.

I have a Blueair for small room and can really sense a difference. I like the app as well to track purity and change settings. So many options out there though.

I have a giant blue air and I love it. Before we didn't have one in a smaller space and I feel some days I was dying. The cost of the filters is kind of pricy though.

I second Levoit, we have almost one in each room. And we also have a Blueair large room. Both are a smart device connected and man the amount of dust the pull is scary.

I have tried and gotten rid of Bluair and levoit- just inadequate performance and louder than I like. I replaced them with Medify and have been very happy with the switch. If memory serves I have an ma-50 in the living room and ma-40 is each bedroom. 

I have 2 Bluair. A larger one in my living room and a smaller one in my bedroom. Do they help? Not sure but my app says I have excellent air quality.

We run 3 in our house, one in the main living area (diy pc fan with hvac filters), and one in each bedroom (blue air brand or something, I think). Also consider plastic on leaky windows (cheap sliders).

The replacement filters cost too much and hold only 4ish months
