* Your country of residence: USA (PNW) * Each room or area's volume, in cubic feet or cubic meters. (You need at least one purifier per room or area.) * Living room: approx 500 square feet * Bedrooms: approx 200 square feet * Your filtration needs: e.g., pollen, dust, cigarette smoke, VOCs, cooking odors. * wildfire season and removal of odors including cigarette smoke and marijuana smoke from neighbors. * Startup budget * We are a single income family so while the budget is flexible a good deal is preferred :) Ideally under $300 for all even if that means 2 in the living room * Yearly budget (electricity + filters). * We pay about $150/m or $1,800 annually for our electric bill We have a 500 square foot living room and probably 200 square feet bedrooms -- Thoughts on this one (one for living room and one for bedroom). We'd need the living room and 1 bedroom covered. Purchasing air purifier for wildfire season and removal of odors including cigarette smoke and marijuana smoke from neighbors. We have AC in our apt. Disclaimer: I have no issue with people smoking cigarettes or weed in their apt, despite a no smoking clause in our lease. However, my spouse has significant respiratory concerns and it's problematic for her.

We eventually bought this Blue Aire in large-- probably not perfect but at half off ($300 total) -- it is what it is after all my research exhaustion. We will likely get a 2nd one at half off today.

I have the Blueair comfort pure 3 in 1 and it is great. A bit pricey but works nice and has heating and fan features as well.

Mostly just fancy fan, it won’t cool a room but it is nice for air circulation during the summer

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 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.

It helps a lot. I bought it due to smoke but I’m happy to get rid of cooking and dog smells. I have one from Blueair.
