COSTWAYAir Purifier with HEPA Air Filter for Large Room, Spaces Up to 800 Sq Ft with Sleep Mode, Air Quality Indicator, Child Lock, Perfect for Home/Office for Viruses and Bacteria

I purchased this purifier in our teenagers room.This is a large and workhouse standing unit that is also silent. The timer is the most used feature on this air purifier so save on electricity usage. When we opened this unit out of the box we forgot to remove the plastic from the two filters inside. At first we thought the noise level was a little high and did not notice much air improvement. Then we took the unit downstairs and removed the plastic bags that covered both of the filters. We placed this in our kitchen while cooking wings using both an air fryer and small fry daddy for a test. What a difference this unit does compared to just fans and having to open windows.The air purifier was returned to our teens room and after 3 days and using with the timer he noticed a difference in smell ( except those where he dropped items into the carpet ) and also a reduction in dust build up on his gaming desk and monitors.The handle is hidden in the back at the top and is deep enough to carry with one hand since this unit is lightweight. I prefer to carry against my hip and leg so it doesn’t drop when goof up or down stairs.

I've been using this purifier for the past 2 months on automatic mode, moving the purifier every few days to different rooms to improve the overall air quality in our 2 bedroom house. We have a cat, and don't dust or sweep every day, but the purifier clearly has enough power to filter cat hair and dust, as you can see by the bottom of the air intake.I was pleasantly surprised the first time when the purifier automatically switched to a more powerful mode while placed outside our kitchen while we were cooking. I wouldn't recommend leaving the purifier in the kitchen due to grease in the air that can contaminate the filter in the long run, but one of the best features is the automatic sensors knowing if your air needs some extra filtering due to smoke, grease in the air from cooking, or a sudden change of air flow from a window/door opening. I would recommend facing the air intake outwards for maximum filtering, instead of having the logo side face outwards.

This air purifier works well, I love the size not too big and not small, it’s the perfect size. I appreciate the child lock selection, (for those of you who have toddlers who loves to press buttons) this is a must! The sleep mode is so quiet which is my favorite part in finding a good air purifier.

Think iT was used when I got it although the filters were in bags they had a brown dinge color like it was used and the red light came on first day I used it I reset filter and red doter change light still on filters are expensive
