Replacement filters for air purifying units can add up in cost over time, but there's no way getting around the fact that air filters need to be replaced on a regular basis. Timely replacement optimizes the performance of your air filtration system. For one thing, it prevents buildup of particulate matter from clogging your duct work, making your air unit operate inefficiently.

For another thing, regular filter replacement keeps your forced-air system from blowing this built-up junk into your home's air supply, which would negate the whole point of your air filtration unit. The reason it's there is to keep your indoor air pure. Thus, you must walk the line between premature replacement, which would waste money, and using dirty air filters, which would negatively impact your home's air quality.

Purchasing Replacement Filters

Replacement filters for your air unit can cost up to $40 and $60 per cartridge. This is especially true if you purchase name-brand filters from the manufacturer. For example, Honeywell, Spacegard, and Trion are well-known names in air filters. You've invested in their filtering equipment because it's among the best in the world. Surely you wouldn't want to undermine the performance of your air filtration system by using a poor-quality, generic air filter.

Luckily, there is an alternative, and one that won't have you compromising on quality. That is to buy comparable filters from a third-party filter manufacturer that specializes in replacement filters for the top brands. In terms of quality, these filters are replicas of the original manufacturer's. The only difference is that they are offered at prices up to 50 percent less than those of name-brand filters.
