Every house has a smell, coming home from travel you will notice your own. During Covid purchased an oversized for my space hepa air cleaner (blue air) with charcoal oder eliminator and since my house has no smell. Zero. Even when I run a scent diffuser it doesn’t smell beyond the room it’s in. I recommend all the cleaning suggestions, this is more long term. Mine runs 24x7 even when gone for a week or more. Some may be uncomfortable with that, but that’s for the insurance subreddit :-).
Large Blueair running 24/7/365 for years now. Own 2 large dogs and it definitely makes for an improvement in air quality
We have Blue Air - a large one in the main living area, which catches kitchen/cooking particulate, and a mini one in each kid room. Costco has two packs of the minis for $99 right now!
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.
Seconding Blueair! We have a Levoit and a Blueair; while I have nothing bad to say about the Levoit, I personally prefer the Blueair (granted, it was about twice as expensive). We've got two medium-sized dogs, and - aside from the clumps of dog hair under the baseboards - you wouldn't know that we had any pets!
