14x18x1 AC / Furnace Air Filter: Premium & Long-Lasting

Filter King premium 14x18x1 air filters are ergonomically designed to provide effective filtration at affordable prices. The filters fit your home HVAC systems and protect against any particles trying to enter via incoming airflow. Such airborne contaminants include everything from fine dust, mold spores, to textile lint and other types of dirt. 

How filters work: Air filters consist of tight mesh weaves/pleats that trap and absorb particles right out of passing airflow as it pumps in. These particles have varying sizes, measured between 5 - 10 microns in varying sizes. The air filter media will eventually become full of the particles they block, leading to problems throughout your home and its air systems. Filter King brand filters provide the filtration needed for homes in a variety of environments, protecting you and your family against several types of airborne particles.

14x18x1 Air Filter Use for Residential Homes

Your home's ac systems work constantly to provide fresh, clean air and prevent the indoor air quality from dipping. Depending on location, your home may face high levels of pollutants or rising levels of allergens during certain seasons resulting in minor symptoms such as coughing to severe allergic reactions. 

Filter King’s premium filters, whether in standard or custom-made sizes, are perfectly made to filter out pollutants such as pet dander, dust mites, pollen, allergens,etc., and thus helping you and your family breathe cleaner air. 

14x18x1 Air Filter Use for Apartments

Apartment air systems bring in fresh air and as the new air cycles in, the old need to cycle out to prevent stagnation and potential breathing problems. Old air becomes dry and hot, causing humidity imbalances, which in turn can cause irritation to your nose, skin, and even damage to your furnishings. A well-balanced HVAC system ensures that relative humidity inside your house is not too low for comfortable breathing. 

14x18x1 Furnace Filter

The furnace in your home pumps in cold air, heats it up (some systems use heat pumps), and then pushes the air through a filter media, before finally distributing it through the supply duct system to your living spaces. The filtration part of the process ensures that the heated does not let any intruding particles through the system. Like other air systems in your home, the furnace filters will eventually be filled with trapped particles that hinder airflow. A dirty furnace filter is not just a growing issue, it has the ability to become a dangerous one as well.

A dirty furnace filter leads to issues similar to dirty air filters in other systems as well, primarily with the problems surrounding its blockage of airflow. For a furnace, restricted airflow means the heated air is unable to effectively pass through the filter and the home's temperature will fluctuate in response. The trapped air also creates a temperature issue with the furnace itself, causing the heat to rise to levels that may severely damage the system. Furnace repairs are costly, with air filter maintenance only being a fraction of the cost.

MERV Rating 8, 11 & 13: Which Should You Use For 14x18x1 Air Filter?

An HVAC system is at its best when the filters are replaced regularly. While it’s advisable to replace your 14x18x1 air filter every couple of months, the environment and health considerations may dictate otherwise. Homes in areas with high levels of pollution or allergies tend to go through filters at a much faster rate. Similarly, homes with allergy sufferers. 

Filter King’s superior 14x18x1 furnace and ac filter can last up to 3 months. For most normal homes, a MERV rating of 8 usually suffices. However, for homes with allergy sufferers or smokers, a higher MERV rating is recommended.

Standard: MERV 8 Filter

For most American homes, MERV 8 filter is usually more than OK since it can block up to 90% of airborne contaminants such as dust mites, mold, and pollen. However, for homes with pets and people with allergies, asthma and other breathing problems, you may have to consider using MERV 11 or 13 rated filters. 

Good: MERV 11 Filter

MERV 11 filter can trap approximately 95% of all airborne particles between 3-10 microns. With it, you can expect to remove the usual household contaminants such as dust, pollen, mold spores. Additionally, you can also expect to remove finer dust particles, pet dander, auto emissions etc. 

Better: MERV 13 Filter

MERV 13 air filters are the highest-rated air filters recommended for household use. With them, you can expect to eliminate airborne allergens, smoke, smog, and virus carriers like coronavirus on top of common household irritants like pollen, mold spores and dust. 

Best: MERV 13 Filter (Titanium)

For odor elimination, you may want to consider using Filter King's highest-rated filter with its specially designed mini pleats for effective odor elimination capabilities.  

Word of caution:  High MERV rating isn’t always the best option. When a filter's MERV rating is too high, then the effects of the tight mesh weaving are often as bad for airflow as a dirty filter is. The lack of effective airflow causes the system to overexert and wear down faster, your home's energy billing increases as well over time. 

Is It Time To Change Your 14x18x1 Air Filter?

Air filter replacement is necessary on a regular basis or the effects will begin to affect the comfort of your home. First, locate the air filters, the owner's manual for the system will provide the location. Once found, take the filter out and find the size number along its cardboard edge. With the right size in mind, your new air filters will be able to effectively replace the old ones and provide a system with fresh, clean air. The process should need repeating every month or so to avoid any air problems in your home.
