AIR DOCTOR 3500 AIR PURIFIER
All Good Care—December 21, 2025
This is the best air purifier you'll find. It automatically bumps up its strength if you have some cooking smoke or even for the one in my bedroom, if it detects hairspray etc. from bathroom it kicks up power. Really a smart and efficient machine. i actually did a little research on purifiers before my purchase. This one had good ratings and I've been pleased with it's performance. The filters are pricey but you only change one every six months and the HEPA only once a year. The price of the purifier itself is reasonable for the square footage and speed of air turn over.
