Spokane Valley homeowners seeking cleaner, healthier indoor air should consider UV air filters. These advanced filters utilize ultraviolet (UV) light to effectively eliminate harmful airborne pathogens like bacteria, viruses, and mold spores. In a region known for its warm and humid climate, where these contaminants thrive, UV filters provide an extra layer of protection against respiratory issues and allergies.

Frequently Asked Questions

When selecting an air filter, it’s essential to consider its MERV rating, which ranges from 1 to 20. Filters with higher ratings offer finer filtration, but not all levels are suitable for residential use.

MERV ratings 16 through 20 are typically reserved for specialized environments like hospitals and cleanrooms. For home use, filters with ratings between MERV 5 and 13 work just fine.

While a higher MERV rating may seem preferable, it’s not always necessary and can potentially hinder your HVAC system’s efficiency. The optimal MERV rating strikes a balance between effective filtration and maintaining system efficiency.

So while the range typically is broad for homes, in Spokane, we recommend a MERV rating between 8 and 10 for your home filter. These filters effectively capture airborne particles, enhancing indoor air quality without significantly increasing energy costs.

If you’re unsure when to replace your home’s air filter, watch out for these telltale signs indicating it’s time for a replacement. These indicators shed light on the crucial role air filters play in enhancing your home’s comfort and how a small investment of time and money can yield significant improvements:

  1. Visible Dust Around Vents: It’s time to replace your filters when you can see visible dust accumulating on and around vents.
  2. Dirty or Clogged Filter: A visibly dirty or clogged filter should be replaced promptly.
  3. Extended Heating/Cooling Cycles: Longer HVAC cycles signal reduced airflow due to a clogged filter.
  4. Higher Energy Bills: Increased energy consumption may result from a clogged filter.
  5. Declining Indoor Air Quality: Worsening air quality suggests an overdue filter replacement.
  6. Hot A/C Unit: Excessive heat from the A/C unit indicates restricted airflow, often due to a dirty filter.
  7. Uncertain Last Replacement: If you’re unsure when the filter was last changed, it’s likely overdue and time to be replaced.

To determine the correct size of your air filter, you can check for the air filter dimensions typically labeled on the side of the filter. Look for two size measurements: a ‘nominal’ size, often in larger print, and an ‘actual’ size, usually in smaller print. It’s crucial to get the right size filter for your HVAC system’s health. A filter that doesn’t fit properly won’t effectively capture airborne particles. If the filter is too small, it will leave gaps for debris to enter, while one that’s too large won’t fit into the slot. Trimming it down isn’t recommended, as it can create gaps allowing contaminants to bypass filtration. Alternatively, you can examine your existing air filter, measure it yourself, or measure the air register or air filter slot to ensure the correct size.

Typically, air filter manufacturers and HVAC experts advise replacing your air filter every 90 days, or roughly every 3 months. However, this timeline may vary based on several factors, including your home’s location (such as dusty or dry climates), the presence of pets, and the age of your HVAC system and equipment.
