Air Filtration Kit 4” with Speed Controller

Awesome, superb quality. This company really cares about quality products. Very quiet at speeds of 1-5, only small levels of noise at 6-10. My bathroom exhaust fan is louder than this though this is moving 4 or 5 times the air with a filter. Would def buy again. Thank you.

Device works great! Had a major odour issue in my apartment and this device has single handed made the odour go away. Even on the low 2 setting. It is pretty silent for the most part! I love that it comes with the cloth filter as well. Well worth the price.

Great product. The pricing is amazing for what you get. I highly recommend this product.

We use our 4” cloud line system for our rodent room (we breed rodents as feeders for our reptiles) and the ammonia can build up to toxic levels quite quickly if not exhausted out. The 4” is super quiet and we use it in a space equivalent to approximately 200 SqFt and vent the exhaust outside. It works exceptionally well for our modest collection of 40 breeders (rotated cycles) and anywhere from 50 to 300 grow-outs at any given time. The more grow-outs, the more critical the filter becomes necessary. It works so well, we normally only need to run it for half of the day unless we are sitting on a ton of grow-outs; in which case, we run it at max power all day.

great product
