Review on RENPHO Large Room Air Purifier for Bedroom - Up to 720 Ft², True HEPA Filter Intercepts 99.97% Dust, Smoke, Odors, Allergens, Pet Hair - Quiet 26dB, CADR 170m³/h by Amanda Reynolds

• Why did I buy this? I have trouble breathing and winter is always the worst for me. People smoke in their apartments and don't open a single window, but I live in the very last apartment in an old building. So all the smoke is entering my apartment and I feel like I can't breathe at all. My old air purifier stopped working so I had to urgently buy a new one. I have other RENPHO products so I trust them. • Advantages: price, compact, powerful and easy to transport. The sleep mode is very useful and not audible at all. • Cons: Can be very noisy on the highest setting and lights can be distracting • Generally, I have another $200 purifier, but the RENPHO is both powerful and expensive. It's powerful enough to circulate the air in the studio. I've had this for 3 days and let it go the whole time. I haven't had any problems so far.
