In general, true electrostatic filters will perform better and last longer than any other HVAC filters on the market. But because there are no commonly accepted standards for electrostatic filter terminology, there are lots of inferior furnace air filters on the market that are being promoted as being electrostatic. We advise you to shop carefully and to make a purchase only after verifying the quality and performance of the brand you're considering. Several companies are producing filters composed of imitation polypropylene and polyurethane media which cannot perform at anywhere near the same levels as genuine electrostatic filters.
We have been careful to do our own homework in this area, and we've made our purchasing decisions accordingly. As you explore our home air filter inventory, you'll notice that we only carry filters from Air Care and BoAir. These two brands have exceeded our standards for product quality, and they are currently the only ones we can sell to our customers with the utmost confidence. When you shop online with us, you can be sure that you'll never get an inferior imitation product.
If you've been using disposable fiberglass filters in your HVAC systems for your entire life, the concept of cleaning a filter may be entirely new to you. As you may have read in other neverbuyanotherfilter.com articles, the process of typical home air filter maintenance is very simple; simply vacuum up the collected dust with a vacuum wand attachment and, if necessary, hose off the filter outside with a garden hose.
But beyond those basic steps, there are a few other considerations to keep in mind. First, when hosing off electrostatic furnace air filters, you should be sure to spray in the opposite direction of the airflow first. This is because the filters are designed to trap particles. If you spray in the same direction as the airflow, you won't be able to push those particles out through the other side; instead, you'll just drive them deeper into the mesh. Spray against the airflow first, and when you're confident that all of the particles have been dislodged, you can gently spray the other side.
It's also important to protect your filter from certain solutions and environments that can reduce its filtering ability. Though you should let a damp filter dry completely before reinstalling it, you should never leave it out in the direct sunlight to dry. Also, avoid using oil-based cleaners on the mesh, as they can eventually build up and restrict the natural airflow.
