We have a blue air blue 3610 (I think that’s the model) in our bedroom. No wifi. It kicks into high gear at all the right times, including a bunch I didn’t expect it to, like when my partner is using airbrush paints in the garage (total opposite side of the house). I picked it because it rated well on Choice and I snagged a clearance type deal on it at Harvey Norman so saved a tonne. Replacement filters aren’t super cheap, but reasonable enough.
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 :-).
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.
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.
