When it comes to air quality, the higher the MERV rating, the better the air filter will be at removing particles. Low-cost air filters usually have a MERV rating of 6 or less, while more expensive options can have a rating of up to 13. This means they can capture much smaller particles, such as bacteria, viruses and mold spores, from the air. Heating, ventilation, and air conditioning systems are not designed to improve air quality in the home, but filters are essential for them to work properly. Cheap fiberglass filters are designed to prevent dust, dirt and hair from dirtying the system.
While they do little to filter out allergens and other irritants, their use keeps the HVAC system clean and efficient. The downside of cheap air filters is that they are not as effective at removing contaminants from the air. This is especially true for large families with pets in the household. You'll have to change filters more often, which will cost you a lot of money in the long run.
The benefits of a high-quality air filter are that it can remove dust from the air and stop allergies, but it also has drawbacks, such as increased costs. If no one in your household has an allergy and you don't have pets or major problems with air quality, for example, an affordable filter can be sufficient. For instance, hospitals use filters rated 16, but that's not necessary for your home environment, and using a filter with such a high rating will increase your energy costs. You can also have a separate filter for the air purifier, which can be a separate unit or one connected to the heating and cooling system.
An electrostatic air filter is a washable air filter that uses static electricity to capture particles. If you can find a reusable filter that captures the types of contaminants you need to filter for your family, you could pay more upfront and save money in the long run. Air filters are also important for people who live in heavily polluted areas, as they can filter out harmful contaminants from the air. In terms of efficiency, pay attention to the minimum declared efficiency values (MERV) classification, which refers to the ability of a filter to capture various particles from the air.
In addition to helping your home's heating and cooling system work more efficiently, an HVAC filter plays an essential role in your home's indoor air quality. Some days are worse than others when it comes to air pollutants, and sometimes the government issues warnings for elderly people, those who are ill or young children. A low-cost air filter can have fewer folds (sometimes referred to as layers), greatly reducing its surface area for trapping impurities. When it comes to the health and comfort of your family, friends and other guests, it's wise to get the most efficient air filter you can afford.
Not only do filters make it easier for people to breathe, they also reduce odors and make your home a more pleasant place to live. Whether you choose fiberglass or pleated filters, the most important thing you can do is change them frequently. It is essential to understand how different types of air filters work in order to make an informed decision about which one is best for your home environment. Knowing what type of contaminants you need to remove from your home's air will help you determine which type of filter is best suited for your needs.
