Review on 🌬️ Horti-Control P DS10 Filter: Optimal Air Filtration for 10-inch Horticultural Systems by Vanessa Johnson

First I received a used filter that had been washed several times and re-oiled with oil. It was obvious it had been used and wasn't sealed in the bag. So I sent it back and got a replacement. This time it was brand new, sealed in a bag and well lubricated with blue oil. When I held the new filter up to the light, I didn't see much light through it except for a few spots. The old and washed filter lets through 2-3 times more light than the new one. This leads me to believe that these filters will wear out over time like most of them. In general, the new one works well and has hardly gotten dirty with constant use in the last 3 weeks. The old filter started leaking powdery white dust from my ultrasonic humidifier, which I haven't used since because of this. I haven't noticed any fine particles collecting on the glass of my air-cooled reflector, so that's a good sign that this filter is working. It needs to be cleaned and re-oiled every few months depending on usage, you can also use any organic oils that are safe for your plants.
