When it comes to air filters, the old adage “you get what you pay for” is often true. If no one in your home has allergies and you don't have pets or major air quality issues, an affordable filter can still be effective. However, the main downside of cheaper filters is that you'll have to replace them more often, which could end up being more expensive in the long run. Cheap filters trap fewer particles that float in the air.
A low-cost air filter can have fewer creases (sometimes referred to as layers), which significantly reduces the surface area for trapping impurities. This means that more harmful airborne pollutants can enter the air conditioning system and circulate throughout the home or office. A 1-unit filter makes it difficult to filter air effectively and ensures optimal airflow and equipment performance. Cheap air filters usually have a low MERV rating of 6 or less, while expensive air filters can have a MERV rating of up to 13. Not only does this save you money, but it's also more practical since you won't have to remember to change your air filters as often. A high-quality air filter that costs a little more can prevent dust and other contaminants from entering your lungs and reduce allergens in the home.
Expensive air filters are made of higher quality materials, last longer, are more efficient at trapping particles, and have a larger surface area to filter. Pleated filters clean the air better than fiberglass filters, but they come with increased costs. If you're looking for an air filter that provides the best possible protection for your climate system and improves indoor air quality, then an expensive air filter is the best option. You may want to consider a washable air filter, as it should last for years rather than months. However, this option has several drawbacks, such as a lower MERV rating, frequent maintenance requirements, and the potential for mold growth on the air unit. Finally, look for online stores that offer discounts for regular shipments of air filters (ours is 5%, for example).
Air conditioning systems are not designed to improve air quality in the home, and filters are important for the boiler and air conditioner to work properly.
