Benefits of Improving Your Indoor Air Quality

There are many reasons to invest in your home’s indoor air quality. Poor indoor air quality can be related to HVAC inefficiency, so one of the biggest differences you may notice is lower utility bills.

Additional benefits are attributed to your comfort and health, such as:

  • Easier breathing
  • Improved sleep
  • Reduced allergy and asthma symptoms
  • A cleaner-smelling home
  • Balanced humidity

Whole-Home Humidifier Installation

Balanced humidity is key for your comfort and health. Humidity above 50% or below 30% can lead to a variety of issues.

With a whole-home humidifier from Len The Plumber Heating & Air, you can ensure that your home has balanced humidity so you can avoid mold and mildew growth from excess moisture and itchy, dry skin from too little moisture.

Air Purifier Installation

Air purifiers are an excellent addition to your home to remove mold, mildew, dust, pet dander, and other contaminants.

When used alongside your traditional air filters, UV and HEPA air purifiers can neutralize virtually all airborne particles, rendering them harmless.

Frequently Asked Questions

What causes poor indoor air quality?

Many things can contribute to poor indoor air quality, including:

  • Fuel-burning appliances
  • Household cleaning supplies
  • Poor ventilation
  • Outdoor air pollution

Do higher-quality air filters make a difference?

Yes. Many homeowners use a 1-inch standard filter. They filter out many contaminants and need to be changed at least every three months.

HEPA filters need to be changed every six to 12 months. They’re made of thin fibers of glass and activated carbon-based material that trap more harmful pollutants.

Can I use a UV air purifier and humidifier?

An air purifier and humidifier target different issues and can be used together. Your air purifier will work to filter out pollutants while a humidifier will keep your home at the perfect moisture level.
