Should I Buy An Air Purifier?

by B.Annie on March 19, 2018

Buying an air purifier makes sense if breathing cleaner air is important for you or your family.  For people with
breathing issues, chronic allergies or other environmental challenges, an air purifier becomes a must.

Examine the products carefully if you are considering buying an air purifier. If it is cheap, you may be looking at a glorified fan. Don’t waste your money. Save up for something that is effective.

Personal responsibility

Before you make the purchase, consider some other things you can do to improve indoor air quality.  These steps can help if you want to lessen the frequency of allergic and asthma attacks. For some
people, these steps will feel drastic but, in reality, they are quite practical.

  • Use smooth flooring in your home rather than carpeting. Carpeting can be “home” for dust, dust mites and even particles from cooking or fireplaces.
  • Upon the arrival of each new season, clean filters in the ducts, air conditioners and air filters. Some of the filters should be cleaned even more frequently, but at the very least, they should be cleaned once a season.
  • Rely on your air conditioner in spring and summer to remove particles from the air that might trigger a reaction.
  • Pets should be kept off the bed and furniture. Ban them from the bedroom and seriously think about limiting the number of pets you have.  Pets not only have their own dander that may be causing you issues, they bring in allergens from outside that can reek havoc on an allergy sufferer.
  •  The most obvious step of all is to stay away from smokers or if you are a smoker, STOP! Send the smokers outside to do their business if they cannot refrain completely.


Once the homeowner takes these steps, she is ready to consider getting an air purifier. The person who suffers from allergies or asthma should remove as much material from the air as possible to avoid irritation of sensitive breathing passages. Even every day allergens  like dust, dust mites and pet dander
should be kept to a minimum.

“Is dust really a problem?” you might ask. Early in the morning or evening, you can sometimes see an isolated shaft of light coming through a window. Look closely and you can
see the dust particles floating in the air. Minimizing those particles can be important to people with breathing issues.

Let’s look at three types of air purifiers: fan-based, HEPA-approved particle filters and ozone-based purifiers.

Fan-based Air Purifiers

As mentioned before, the fan-based filter generally pulls the air through the device and does no filtering. It simply moves the air around and makes no impact on an individual’s breathing conditions. As you might imagine, this device is not as effective as the more sophisticated devices.

Filter-based Air Purifiers


Among the devices to consider when thinking about buying an air purifier are the ones designed to remove allergens through HEPA-approved filters. They can be effective at removing over 99 percent of airborne pollutants including pollen, allergens, smoke particles and dust.

Reading the reviews on these items before buying can be helpful.

Personal stories of users are also instructive as many who suffer from allergies see marked improvement from the use of air purifiers.

The equipment often can be set to run for different cycles, allowing the homeowner to set the machine for more intense air cleaning while she is out of the house, allow her to return to scrubbed air.

Different settings direct the machine for germ-free, normal clean or turbo cycles.

The equipment can also take care of cooking smells and burnt food accidents. Normally those smells can last for a considerable time and seep throughout the house quite quickly.


Producing Charged Ions

The final type of air purifier to consider when purchasing an air purifier is one that allows the user to opt for an ozone-based system which removes germs, dust, allergens and other airborne particles.

It also handles smells and smoke. It does not “mask” smells with fragrance-based chemicals, but knocks the particles out of the air so they will be collected through the normal vacuuming and cleaning process that the homeowner does.

The system does not pull air through a filter but creates negatively charged ions in the air much as thunderstorms and lighting do in nature. These oxygen-rich, natural scrubbers cleanse the air
of pollutants that can be harmful to people with breathing issues.
Because this approach does not use a filter, a single appliance can effectively clean the air in a 3,000-square foot house. It can also clean air in rooms with closed doors.

Here’s the answer to the question “Do I need to buy an air purifier?”

The answer is, “How important is clean air to your health?” For those to whom clean air is important, several effective air purifiers are on the market.  Check with your HVAC provider for his recommendations.



Your HVAC professional can install the purifier into the home’s air conditioning system so the air is continually being purified and circulated throughout the house.
