Best air purifiers for weed smoke in 2022

Whether it is in your room, your parents’ house, or on the streets, it is not easy to hide weed smoke or smell. Many people try different methods to keep marijuana smoke at bay when puffing.

For example, some people steam up their bathrooms before smoking. Steam is heavier than smoke, hence it will push the smoke away.

However, one practical option you can go for is to use the best air purifier for weed smoke.

Getting rid of marijuana smell and its particulates requires specific technologies. While regular air purifiers can work, most of them are not 100% efficient.

That is because they do not have the technology to deal with residual CBD and THC from cannabis. Only a more advanced smoke purifier for weed can do that.
