What Happens When You Don’t Change The AC Filter
You should not overlook the humble AC filter. It is a key player in the success of any modern HVAC system. Knowing their benefits and when to change them will convince you to not shrug off changing the filters, and this will help you maintain a healthy, well-functioning home.
The Power of Clean Filters
- AC units work better when filters are clean. It’s true! The intake of air is easier for clearer filters, which allows the unit to cool the air more evenly and efficiently.
- Pollutants in the air are nothing to sneeze at. Whether it’s dust, animal hair, or particles of dirt, unfiltered air can damage your health. This is especially true for anybody with asthma, allergies, and other conditions which make breathing difficult.
- Filters extend AC units’ lifespans. Akin to how less pure water can cause more buildup in pipes, less pure air can cause buildups in the ventilation and machinery of your AC if the filter is no longer effective.
When Should You Refresh Your Filters?
There is no perfect answer for this question. Most professionals suggest that between 30-90 days should be the ideal for filter replacements. The large degree of variance depends on how many people and pets use the space which the filter supports. Also, the higher the quality of the filter, the higher it’s MERV number (Minimum Efficiency Rated Value), the longer you can use the same filter.
But there is another option beyond simple replacement. There are multiple brands which produce reusable, washable filters. They can be as good as most disposable filters while being more environmentally and economically friendly.
