Keeping your HVAC system running smoothly and your indoor air quality strong means using good-quality filters—and changing them regularly. Choosing the right type of air filter requires a little more thought than picking out the first (or cheapest) one that fits your system. Some filters need to be changed more often, while others might be more suitable for those with respiratory illnesses and allergies. Here is an overview of the most common HVAC filters in Mabank, TX, so you can make the right choice for your home:

  • Fiberglass: One of the least expensive options available, fiberglass filters are disposable and need to be changed about once per month. These filters do the bare minimum to filter out dust and pollutants, but will probably not be sufficient if you have asthma, allergies or other respiratory issues.
  • Pleated: Pleated filters are a step up from fiberglass filters in Mabank, TX. They’re made from pleated polyester or cotton—and the more pleats, the better they’ll be able to filter out contaminants. This type of filter can last as long as 90 days, depending on the outdoor air quality. They’re usually disposable. Note that your HVAC efficiency may decline because the pleats are so effective at filtering the air.
  • Electrostatic: Electrostatic filters use fabric or paper and an electrostatic charge to attract contaminants. Dirt, dust and allergens are attracted to the charge, so they’ll “stick” to the filter better. This can filter out tiny particles, making it a great choice if you suffer from allergies. This type of filter comes in both disposable and washable versions. They tend to be more expensive than disposable fiberglass or pleated filters, but they’re better at filtering out pollutants.
  • Washable: Washable filters are an environmentally-friendly alternative to disposable filters, and many types have a washable option. The most important thing to remember with this type of filter is that they need to dry completely before being replaced in your HVAC unit. Otherwise, mold, mildew and bacteria can grow on the filter and get spread around your home. You might want to purchase two washable filters so a clean, dry filter is always ready to go.
  • HEPA: HEPA filters are the gold standard for people with respiratory issues. HEPA stands for “high efficiency particulate air,” and these filters can screen out about 99.7 percent of air contaminants. That makes them highly effective at keeping the indoor air quality clean and safe for everyone in the house.
  • UV: Finally, UV filters can kill pathogens and microorganisms in the air using ultraviolet light. This type of filter needs to be used in conjunction with another type, because they do not screen out dust and other contaminants. However, they’re great at preventing the spread of illness.
