Do you sneeze a lot at home?

Maybe you’re probably about to have a cold or probably your home’s indoor air quality is low and has a high level of contaminants everywhere.

This video may be a bit funny but seriously, when sneezing problem keeps recurring inside your home, it has to stop!

A deficient Indoor Air Quality inside your home could lead your family’s health at a very serious risk. It is ideal to find ways on how to provide comfort and energy efficiency in your own home. The best way to start that is to properly maintain your HVAC systems or find DIY solutions for a cleaner air and maintain its quality at best.

According to

In an Australian study, it is estimated that the cost of losses of worker productivity, higher medical costs and increased absenteeism already exceeds $12 Billion of annually caused by unhealthy indoor air.

There are lots of HVAC, DIY hacks and IAQ monitoring systems available but no matter what kind of device or systems you use, there’s always a possibility that you won’t meet the efficiency level at a good indoor air quality rate.

We have come up with solutions for you in order to maintain the air quality in your own home.

Here’s Top 5 Best Picks of Ways on How to Improve the Indoor Air Quality at Home



Yes, you’ve read it right. Houseplants were analyzed by NASA in 1989 as natural air purifiers that remove a group of harmful chemicals lurking inside your home.

The group of plants chosen for this study was determined by joint agreement between NASA and the Associated Landscape Contractors of America. The chemicals chosen for study were benzene, trichloroethylene, and formaldehyde. The results show that plants can play a major role in removal of organic chemicals from indoor air.

These are just few of the many houseplants recommended by NASA studies.

  • Bamboo Palm
  • Sansevieria
  • Areca Palm
  • Spathiphyllum
  • Spider Plant
  • Golden Pothos

Basically these plants will naturally remove pollutants such as carbon monoxide, toluene benzene, formaldehyde, trichloroethylene, and xylene.



Having an air purifier or air cleaner at home also helps since it filters most pollutants such as dust, smoke from candles and fireplaces, and even outdoor pollutants that pass through your door and window into your home.

Room models of air purifiers have annual operating costs of $150 to $200 for filter replacement and electricity (with the majority of that cost being for filters). Filter prices can range from around $10 each up to about $100 (with some priced well into the hundreds). Some units use a pre-filter to capture large airborne particles before they reach the HEPA filter, possibly extending its life and can range from around $10 to $35.

So before deciding of having one, always consider the operating and maintenance cost.


Eliminating the sources of indoor pollutants has always been the best method there is in order to control the air quality in your home.

These include:

  • Preventing from smoking indoors
  • Avoiding the use of pesticides inside the house
  • Avoiding the using chemically-based cleaners
  • Changing the filters in your appliances regularly especially, in your HVAC system.
  • Eliminating the use of incense, candles and liquid fuels.

And some sources, like gas-emitting stoves can be adjusted to minimum and asbestos can also be sealed or enclosed to some place safe.


Ventilation can help control indoor ventilation and remove or dilute indoor airborne pollutants coming from indoor sources. With proper control of ventilation, it reduces the level of contaminants and improves indoor air quality.

Best way to ventilate your home is by making sure that air may enter your home through:

Natural Ventilation, such as windows and doors

Mechanical means, such as outdoor intakes associated with heating, ventilation and air conditioning (HVAC) system

Infiltrations, a process by which outdoor air flows into the house through openings, joints and cracks in walls, floors and ceilings, and around windows and doors.

By the means of controlling your ventilation, the risk of bad air circulation inside your home reduces and moderates good IAQ instead.

For more information about whole house ventilation system options, see the U.S. Dept. of Energy’s Energy Saver: Whole-House Ventilation.



With the use of indoor air quality monitors, you can conveniently monitor carbon emission and other pollutants inside your home.

You can now monitor the elements using these devices. Elements, such as:

  • Volatile Organic Compound (VOC)
  • Carbon Dioxides and Monoxides
  • Dust and Gas emissions

Some of these devices were designed to integrate with your mobile so you can also monitor the stats through your smartphones.


Maintaining your house clean and checking your HVAC filters and ventilations regularly is still the best way there is. Get rid of the chemicals and pesticides inside your house or seal those and place them in your garage. You may also ask your HVAC contractors to do free checkup on your HVAC system or even do some IAQ testing.
