Review on Reduce Household Allergens With Premium Pack Of 20 Air Vent Filters For Home by Rob Bishop

I bought specifically because I have neighbors that smoke, alll kinds of stuff every hour of the day ( from 2am everyday man) and it funnels through our vents all the time!So I bought these just for that reason, however it helped stave off dust.I had to cut the sheets because it was too wide for my vents. It is easier to cut through even though filters were slightly thick. However, the 1st day of putting these up - you couldn't smell a thing!But the second day, you could smell every bit of my neighbors 🚬. So I put up another layer, and it's the same thing - 1st day no smoke, next day pure, fresh, sickly smoke.
