The only downside is, with a CADR of 83, it’ll take time for this device to cover 500 sq., ft. Yet, we’d say a little waiting is acceptable because of the great filtration it provides.

This product comes at a very cheap price, basically even half of the cheap models out there. So I’d say the filtration and air flow you get is decent. Also, it’s safe because it doesn’t emit ozone. As for the night light, it can’t be shut down, so it’s something you have to live with. But if you accept this little downside, you’ll get greater value for the money compared to other products.

10. PARTU Air Purifier | Best Room Air Purifier For Mold

Partu is yet another portable air purifier model. It comes with a stylish but compact sleek black design and slope-like top. But don’t get fooled seeing the physique. With a powerful motor, high CADR ratings, and three-layered filtration, this one doesn’t fall far behind the top models.

Bottom Line
One of the major problems with cheap models we discussed earlier was the night light that can’t be shut off. This one has a lighting setup consists of 7 lights and it can be shut off. The memory function is also a convenient feature. It works well within the space of 160 sq. ft. But I’d say the price is already low for such great features. And it’s still better promising to deliver big and failing.
