Air filters – types and cost
When it comes to air quality, there cannot be any compromises. This is why it is important to figure out what type of air filter matches your needs perfectly. This can be done by understanding the various types of air filters and how much each costs. You can always cut down on costs by shopping online and using air filter coupons. But first, let’s take a look at the different types of air filters.
HEPA filters
High-efficiency particulate air (HEPA) filters are the most reliable and effective ones among the lot. They filter out 99.97 percent of dust, mold, and other particulate matter from the air.
UV filters
As the name suggests, these filters use ultraviolet light to destroy any germs, viruses, or bacteria in the air. However, they are not quite effective in keeping out dust particles and allergens. Therefore, they are often used in combination with another filter. They cost anywhere between $60 to $225. They can be hazardous to the human body in the long run.
Washable filters
Washable filters are environment-friendly and can help you save a few bucks. This is because they last for a long time, are easy to maintain, and can be easily installed at home. They have to be washed once every few months and dried before being installed back into the machine. They cost anywhere from $30 to $60 or higher, but are a great investment as they are long-lasting and efficient.
Spun glass filters
Spun glass filters are commonly used for heating, ventilation, and air conditioning (HVAC) systems. They are cost-effective and are great at filtering out dust and debris. However, they do not catch smaller particles like bacteria or allergens, thereby being a poor choice for those with respiratory disorders and allergies. They cost upwards of $10, and can be maintained and disposed easily.
Electrostatic filters
This type uses electricity to keep out dust, allergens, and other airborne particles by attracting them. The good thing about electrostatic filters is that they can be replaced as well as reused. Moreover, they are cost-effective and quite efficient at filtering allergens, and hence, a great choice for people with frequent allergies and breathing problems. These filters start as low as $13 and can go up to $1,000 or higher.
