Comparing 4 Methods of Indoor Air Quality Control

germs-virus-dark-backgroundNot sure which method of indoor air quality control is right for your home? There are a lot of options on the market today, and we’re here to help you navigate through a few of our favorites. Whether you decide to stick with a high-efficiency air filter or a new UV light system, be sure to consult with a local HVAC technician first!

#1: Air Filter

Every home’s air conditioning and heating system includes an air filter, though some are more effective than others. A media filter is able to trap most of the particles moving through, up to a certain size. Air filters are measured via MERV ratings (minimum efficiency reporting value), and a higher MERV means a more effective filter.

Pros

  • This is the least costly method of air filtration.
  • You must change your filter regularly, but this is necessary no matter what your indoor air quality needs may be.
  • A stronger filter may be available than what you have now.

Cons

  • A stronger filter may cause trouble for your air conditioning system, blocking airflow into the system.
  • Air filters have great limitations in the size of particle they can filter, as this isn’t their primary purpose.

#2: Electronic Air Cleaner

An electronic air cleaner that’s installed within your ductwork works a lot differently than a filter. While some may have filtration media built in, this is not the primary feature. Instead, modern electronic air cleaners release ions with a negative charge. These ions add a charge to dust and other allergens in the air, which become attracted to surfaces of an opposite charge—namely, a set of metal plates within the system.

Pros

  • Able to rid the air of many types of contaminants of all different sizes.
  • Will not interfere with airflow.
  • Quiet operation.

Cons

  • May not fit within your budget.

#3: UV Air Purifier

Ultraviolet lights can also be installed within the HVAC system. The UV rays are able to kill certain microbiological contaminants on contact. This includes small living things like bacteria and viruses. Once they are killed and sterilized, they are no longer harmful to breathe in.

Pros

  • Despite some concerns, the UV rays are not harmful for your family, and are safely contained in the HVAC system.
  • Especially useful for people with immune system disorders.
  • Effective at reducing airborne illness.

Cons

  • This air cleaner will not remove particulate from the air.

#4: Duct Cleaning

Duct cleaning is a service offered by select heating and air conditioning companies. Technicians use brushes, vacuums, and other techniques to clean out the inside of the ductwork, which may be full of dust, pet dander, and other types of particulate.

Pros

  • Clean ducts means a cleaner home. Duct cleaning may also reduce dust around the house.
  • Many people note a significant change in air quality after duct cleaning.

Cons

  • The process takes time and preparation.
  • There are scam artists out there who do not complete the work properly.
