Q: "Currently I am using disposable furnace filters. I am considering the Envirosept but wonder if this performs any beter than the washable furnace filters. We do have allergies to dust. Thanks." Frank
Answer: I have two answers, one based upon personal experience here at our Safe Home Products' office and one based upon information from the manufacturer.
At our offices, we have numerous printers plus the dust and dirt that drifts in from the frequent comings and goings into our large warehouse. We tried a fiberglass filter initially and then replaced it with a 1625 Envirosept furnace panel. The amount of dust that collects on desks, monitors, etc. decreased significantly with the Envirosept. We do have to change the filters about every three weeks. I, too, am allergic to dust plus pollen and more. The EnviroSept keeps the air clean so I'm not sneezing!
Second, the manufacturer, Aqua Air Technologies shares that there is no way to compare the EnviroSept to either the frictional electrostatic filters or the standard fiberglass ones that you throw away. Mike explains that the Envirosept is up to a thousand times more effective under normal operating conditions. "In theory, the plastic/glass strands are supposed to develop a static electric charge as the air passes through the filter, much like when you comb your hair. However, you need very low humidity to create any type of low level static charge. This charge is quickly lost as soon as the filter collects any dust, which insulates the plastic/glass strands and prevents the generation of any static charge. It would appear that the only benefit these filters offer is that they are permanent. Further, you do have the dirty task of washing these filters every two-three months. In addition, these filters have been known to cause major air restriction problems after several years that may damage your heating/cooling system."
Our unit is 5 years old and we've experienced no problems. The Envirosept units come in many sizes. All the units we sell come with 14 filter pads, enough for most people for at least 1 year. The power used is minimal and the cost cannot be beat! Changing the filters is easy. Just unplug the panel. Slip it out. Open the clips. Remove the dirty filters, replace into the one inch slot after fastening the clips and plug in. Wipe off the grids with a damp microfiber cloth if necessary and let dry before refilling and replacing.
Thanks for your question.
