I can see your steaks and chicken in the house and not worry about smoking up the house because I don’t have outside ventilation sure I can open a window but who wants to do that while you’re cooking and you have central air turned on so this thing will quite literally eat the smoke that you produce while you’re cooking and it does it very quickly within 20 minutes. The whole house is clear out. This machine is very expensive, but it’s also worth it. It’s quiet it sits in the background idling waiting for the next smoke event when smoke appears it eats it then it goes quiet again. You never know this thing is there give it a corner set it and forget it. It works perfectly great design great machine buy it with confidence. It works well.! As filter replacement goes, I’m not sure yet. I’ve only had it for a couple of months, but from the looks of it, the filter will last six months to a year like they say.. Review: Yes! - This is such a great air filter! I love that it gives you the ppm reading. It also has a switch to turn off all the lights if you use it in a room to sleep. ## Features - AERODYNAMIC AIR PURIFICATION HyperVortex air technology optimizes airflow, enhances filtration efficiency, minimizes airloss, all with remarkable speed and whisper-quiet operation at 21.6 db.
