Why Should You Invest in an Air Purification System?

Clean Air Sign

Keeping your indoor air quality (IAQ) good is essential to your family members' health and comfort. Unfortunately, the air inside your home can be highly polluted, even much more than the air outside.

Contaminants in your indoor spaces are the reason you may suffer air conditioning sickness. The condition results from your AC circulating airborne allergens such as pollen, bacteria, mold, mildews, and smoke.

An air purifier can be the solution to your indoor air quality woes. Here are three gains you can expect from investing in an air purifier.

Fewer Contaminants and Allergens

The top benefit of an air filtration system is to remove contaminants and allergens from your indoor air. The best air purifiers filter at least 99 percent of contaminants from the air you breathe. This way, you don’t need to worry about the dangers of indoor air pollution.

No Unpleasant Odors

Some of the particles floating in your indoor air can cause your living space to smell bad. When making meals, cooking grease particles in the air can cause bad smells, making your indoors uncomfortable. An air filtration system can trap these airborne particles, leaving your home smelling fresh at all times.

Reduced Symptoms

Unclean indoor air can trigger such symptoms as sneezing, headaches, dizziness, lethargy, and nausea. Since an air purifier keeps your air clean, these symptoms become a thing of the past.

What Makes an Ideal Air Filtration System?

Air filtration systems are not made equal. How do you choose an air purifier that gives you maximum benefits? Check the following qualities.

Size Compatibility

Every air filtration system is designed to serve a room of a specific size. Before you start shopping for an air purifier, find out the size of your home. Talk to the customer service representative to get a purifier that’s compatible with your room size.

Generally, you want to buy a model that can effectively serve a slightly larger room. This makes the air purifier effective even at lower settings, saving you on energy bills.

Noise Level

Some air purifiers can be quite noisy, disturbing the comfort of your home. Opt for a system with a noise rating of 50 decibels or lower. Such a purifier is as quiet as your refrigerator, meaning that it won’t disrupt your sleep at night.

Check for HEPA Filters

If you opt for an air purifier that has filters, insist on true HEPA filters. These filters are extremely efficient and can capture the most minute pathogens. These filters are also highly reliable when it comes to keeping your indoor air fresh and free of odors.

Clean-Air Delivery Rate (CADR)

Every air filtration system has a CADR. The CADR indicates the system’s overall purifying speed for a room of a given size. Specifically, CADR specifies how quickly a purifier can filter smoke, pollen, and dust, which are the commonest indoor air contaminants.

A high CADR implies that a purifier can clean the air quickly. The ideal CADR for an average-sized room is between 300 and 400.


Air filtration systems need proper maintenance to serve you well for a long time. However, some air purifiers require more frequent maintenance than others.

Maintenance costs typically depend on how often you need to replace the air filter. Some air filtration systems come with washable filters, especially those with UV lights. Such air purifiers, however, use more watts to function, which means higher power bills.

HEPA filters are more effective and energy-efficient. However, you’ll need to replace them every three months.

What Are the Best Air Filtration Systems in the Market Today?

Now that you’ve seen the benefits of an air purifier and what features to look for when buying one, it’s time to look at some of the best options available today. Here are our five top picks.

Airdog X5

Couple In Kitchen Using Laptop to Research Crystal Heating & Cooling iWave

The Airdog X5 is one of the best air purification systems in the market that work without a filter. The purifier uses an entirely different technology. This technology is known as ionic filtration.

The pre-filter first traps larger particulates, including pet dander and pollen. Air then flows past an emitter that destroys all particulates using an ionic field.

The biggest problem with purifiers that use ionic filtration is that they tend to emit ozone, which can have serious health risks. To mitigate this problem, the Airdog X5 has a catalytic layer that seriously cuts down ozone emissions.
