The most obvious method to determine what type of furnace filter you need is to check the part number or size presented somewhere on the old filter.
It's important to change your home furnace filter regularly for two reasons.
First, the condition of the air you inhale will suffer if the filter gets dirty. A tackled filter blows dust and other contaminants hovering in the air. That is especially unpleasant if you experience allergies.
Second, a clogged filter means your system has to work harder than it should. It consumes more energy, which results in higher bills.
Luckily new filters are a fast and easy solution, but picking the correct one can be a bit complex. Following is a purchasing guide and can give you more knowledge you need when replacing the furnace filter.
If you cannot obtain a filter part number or dimensions, use a tape measure and write the exact dimensions of the filter you are trying to replace.
The length, the width, and the depth. A manufacturer might say 16" x 25" x 5" on a filter, however, in reality, the filter measures 15 5/8" x 24 3/16" x 4 15/16".
Dimension: Prior to order a new filter, measure your current filter and make sure you buy the exact replacement.
MERV: The minimum energy reporting value is the rank you'll normally notice, the scale (MERV 1 to MERV 16) that the largest manufacturers use. For houses, MERV 8 to MERV 12 are the most suitable. At the lower end, the filters catch pet dander, pollen, dust mites, and so on. They're filtering smoke, very fine dust, and microorganism.
Some manufacturers for instance trap 95% of airborne particles. This is especially true of washable filters, Washable filters are not covered by MERV ratings so it is better always go by the MERV grade.
Pleats: Most filters are pleated since they have a more covering space to catch airborne particles.
Hypoallergenic: Some manufacturers produce hypoallergenic filters.
Electrostatic charge: It acts similar to a magnet, pulling particles to the filter exterior. It can serve for the filter's lifetime.
Charcoal: Can be added to filters to help grasp smells.
Antimicrobial: To provide extra protection antimicrobial elements can be added to the filter fibers.
HEPA: HIgh-efficiency particulate air filters catch extremely small particles, which sounds ideal if you have allergies. Unfortunately, these filters are too dense for most furnaces or air conditioners.
Fiberglass (MERV: 2-3) cheap filters allow more pollutants to cross into the furnace than other materials.
Polyester cotton (MERV: 6) disposable air filters can be more affordable for the elimination of small particles, make sure you replace them frequently.
Washable filters (MERV: 8) Environmentally friendly option, not a good choice to catch microscopic particles. Need to be washed regularly.
Electrostatic cotton and paper (MERV: 10) gives great filtering features natural replacement. They are a more costly and safe choice for houses who have pets or smokers.
High-efficiency pleated air filters (MERV: 13-16) The most costly although they have excellent filtering abilities. Commonly practiced in hospitals. It has a high benefit for people with respiratory conditions.
It is mostly recommended that you replace your furnace filter every three to four months. But in case you taking care of pets, we recommend you replace it more frequently. Renovation and construction in the area can also enhance the quantity of dust and debris caught in the filter. In this case, we advise that you check your home furnace filter every month.
