I have one and think it is worth $50. I got it at Blueair and it was on sale for $300 or so off. It's a very expensive air purifier and three filters are need. If you want odor control, too, you must get the [Classic 500/600 Series DualProtection Filter](https://www.blueair.com/products/500-600-series-dualprotection), as opposed to the filters that just clean the room. They range from $120-150 for three, depending on where you buy them online. The Blueair website even has a subscription plan where you get a discount for subscribing.
I'm using it in a foyer which is connected to a living room and dining room, and it works fine. The foyer is right off the breakfast nook and kitchen, and it does an excellent job eliminating cooking smells that drift into the foyer and can travel upstairs. The first two speeds are quiet, but the third highest speed is very, very loud. I also have the Blueair 211+ and 211 Auto in other rooms and really like them, too. If I need air purifiers in the future, I will always buy Blueair.
I have two Blueair purifiers that can get very loud on the highest setting--the 211+ Auto and the Classic 500/600. The latter one was discontinued and the 211+ can still be bought at Amazon, but not at Blueair. Finding OEM filters is no problem for either. You might also consider a sound machine that has fan noises and can get very loud. The loudest and best one I have found is the one below. It has 10 fan sounds and 10 white noise sounds, and the only machine loud enough for me.

The Classic Blueair models with carbon filters work fabulously, yet I have only seen them priced as low as $300 when on clearance. You can still easily get filters for clearance models, though.
Used purifiers can be a good deal, but a new filter for this model is well over $100 so your cost of ownership is going to be expensive going forward. Need to make sure you’re ok with those costs
BlueAir has almost exclusively switched to circular filters, so there’s always a chance they will stop producing replacement filters for this model at some point.
Also, purifiers are not designed to eliminate odors even though they market them that way. They can help, but it’s not going to make a huge difference. Also you have a very large space at 800sq ft, so you will most likely need multiple units to properly clean your air
We use BlueAir Classic, they’re quite effective and are WiFi enabled. The companion app is sometimes frustrating to use but it’s outweighed by the fact that they have an API and can be automated. So I have the purifiers run a different speeds based on the values of our IKEA Vindstyrka.
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.
