Air filters are an important part of any HVAC system. Choosing the right type of filter promotes health and provides your family with clean air. Choosing an incorrect filter, on the other hand, can greatly impact the energy efficiency of your home. Today there are dozens of different filters available to choose from, and every single one of them comes with its own set of pros and cons.
Finding an air filter that’s 100% right for your home can be a challenge. Here are a few quick tips from our HVAC specialists at OK Heating about how to choose an air filter that will meet all of your home’s needs.
Reusable Filters
Many of the air filters commonly used in heaters or air conditioning units are disposable. However, it’s not unusual to come across reusable varieties. These filters cost a little more than their disposable counterparts, but because they don’t have to be replaced the higher initial cost is easily recouped. The main drawback for reusable filters is that they’re not as good as disposable filters when it comes to cleaning your air.
Choosing Sizes
The size of air filter necessary to address your heating or cooling needs can vary from one manufacturer to another. Most units will function with standard sizes, but there are exceptions to this rule. For the best results, it’s always a good idea to consult your product manual and check its filter size specifications. Alternatively, you could also call on an HVAC professional to help you find the right type and size of air filter.
Filter Ratings
Filters are graded by their MERV (minimum efficiency reporting value) rating. The higher the MERV rating, the better the filter will be at trapping very small, fine particles, bacteria and–with high enough MERV ratings–even viruses. However, you can’t simply choose the highest MERV for your air conditioner or heater, because eacj unit has a maximum MERV value they can support. Ask your HVAC technician if a filter’s MERV rating is right for your system.
