How often do I need to replace the air filter on my (Airmax) Aeration system?
Mike – Flat Rock, MI
First, for people strapped for time, we’ll go with the short answer. Under ordinary circumstances, we recommend filter replacements every six months. If you live in a dry, dusty environment, it’s best to change the filter every three to four months. For Airmax Filters, we strongly recommend Airmax Silent Air Black Air Filters (Complete), and Airmax Silent Air Replacement Air Filter Elements for routine replacement.
Now, for those who want the rest of the story, here’s the long answer, which, incidentally, also makes for fascinating cocktail party conversation. To make sense of our recommended filter replacement schedule, it’s important to understand why it’s even necessary at all.
First and foremost, regular filter changes will prevent the premature failure of your filter compressor pump. As it turns out, filter pumps are designed to perform best with clean filters. When filters become clogged, the compressor is forced to work harder. When it works harder, its wear parts are subject to greater wear and tear. And if a filter is left unchanged for too long, an overworked pump is likely to fail. Accordingly, given the cost of replacing a pump, regular filter changes are a much more economical alternative.
In addition to the stress they place on pumps, dirty filters won’t allow the compressor to do the job they’re intended to do, circulate pond water. As a result, the entire pond ecosystem feels the effects. With regular filter changes, pond water is safer for fish and plants, and clearer and more enjoyable for the people who care for them.
Occasionally, our customers ask whether filters can be cleaned and reused. While it seems like a logical option, filters can’t be effectively cleaned – and their performance is significantly compromised. We also strongly discourage the installation of a wet element in a filter system, given the potential to further stress the pump and to unintentionally introduce foreign contaminants into the pond.
As an economical alternative to filter cleaning, we recommend the use of Airmax Silent Air Replacement Air Filter Elements, rather than installing a complete filter unit. The savings are significant – and the filter system will be ready to perform flawlessly for another three to six months.
