We carry discount air filters in 1-2 inch standard sizes, and 3-5 inch media sizes. Our air filters are great and work well in HVAC systems, furnace and air conditioner systems. If you are looking for a custom size air filter you can request that we make a special size for you. As always, we offer free shipping and returns on all of our discount furnace filters.
I have been using washable filters for 15 years. They are simply blasted out in my driveway with a hose (opposite of airflow), drained about 10 minutes and put back in the furnace. The furnace dries the filter out in minutes, so bacteria is never a concern. We wash them once a year, as we only run the furnace for about 3-4 months in the winter and only then about half time (live in California). Not only does it save replacing them, but saves a trip to the store, which is probably the most environmentally part. I recently had the furnace looked at by an installer and he stated we had very little dust buildup since it was last checked 9 years ago. If we need clean air in our house, we open it up for an hour or two - on warm days of course. Simple. Washable filters are cheap and environmentally friendly. Think about what happens to all those disposed of filters you toss!
Update 04/28/2018: This is actually an old update, but this video wasn't getting much traction at the time, so I didn't feel the need to provide one. The Enbridge Obundsman reached out to me to get more details of the case. After I discussed everything with them, they said they would perform and investigation and get back to me. After about a week, they called me back and said the investigation would be performed internally from here on out. They gave me no details of of what happened or if any changes are being made. I am under the impression that they changed absolutely nothing. I informed them that there are many other cases of the same type of fraud as many other victims have reached out to me in a similar situation. They said due to privacy reasons, they cannot discuss the cases with those customers and everything is dealt with on a case-by-case basis. It makes no sense to me why they would deal with something as serious as fraud on a case-by-case basis. It should be taken a whole and if there are multiple cases of fraud, then the company should be banned billing through Enbridge. Due to Enbridge not taking any action, they are essentially helping this company commit fraud. I hope this video can shine some light on the many victims falling prey to this scam and changes will be made in the future.
Check the outside of the housing for buildup of debris, which can impact the efficiency of the unit. Grass clippings and dryer lint particularly can foul the grates. Be careful not to dent the heat exchanger fins, if exposed (more common on older units). These look alot like a car radiator, or the outside of a window A/C unit. Keep the area around the unit free of plants and materials, to help the air to flow freely for best efficiency.
