SINORIKO Auto Mode 1h/2h/4h Timer air purifier

The SINORIKO plug-in air purifier was one of the top performers in our testing. It’s thinner and lighter than most air purifiers, which makes it easier to move around. It has a simple dial with only four settings: 30 minutes, 1 hour, 2 hours, and 4 hours.

If you don’t need to set specific time intervals, this purifier is great for a kid’s room or for people who don’t like fiddling with complicated settings. It’s also very affordable.

This purifier has a few drawbacks, however. First, it uses a fan to blow air out of the front of the unit, so it can only clean air that’s directly in front of it. Second, we noticed a strange burning smell when we used it—though we couldn’t find any evidence that this purifier uses ozone or UV light, both of which can cause off-gassing.

But if you want an easy-to-use purifier or you have a small space where you just want to clear out odors and not germs, this is a good buy.

SINORIKO Auto Mode 1h/2h/4h Timer air purifier FAQs

No. It is a UV air cleaner, not a scent diffuser.
You don’t need to turn it all the time. When you want to clean, you can open it. After using it, remember to open the window to circulate the air.
4 hours of purification is enough to make the air become fresh, actually 2 hours, no need to open for a long time.
