Do Air Purifiers Really Help with Allergies?
The short answer is yes, air purifiers positively help with allergies. In fact, effectively cleaning the air in the home has been shown to significantly reduce the severity and frequency of occurrence of allergy symptoms in the majority of sufferers, regardless of whether their allergies were caused from pets, mold, asthma, or pollen.
While air purifiers can be extremely effective in treating even the most severe allergies, they are not a one-stop solution. That’s because larger allergens like pollen and pet dander only stay circulating in your air for so long. If not properly filtered out beforehand (like in homes without air purifiers, or those that are not using an appropriately sized unit), these microscopic particles and sink into your flooring and furniture where they will rest until disturbed in the future.
To keep your home as allergen-free as possible, you need to use one of the best air purifiers for allergies to keep your home’s air clean, as well as practice good, routine cleaning of carpet, sofas, and anywhere else allergens may reside.

How Do Air Purifiers Work?
Air purification technology is nothing new. We’ve been using cloth, cotton, and other mediums for hundreds – if not thousands – of years to keep harmful particles out of our lungs. In the most basic form, a doctor’s surgical mask or the respiratory devices that firemen wear in the field are both examples of air purifiers.
Early generations of electric air purifiers used fan blades and negative pressure to suction contaminated air into the device and through a fine cloth or synthetic filter. The filter would then trap larger particles floating in the air, resulting in a much cleaner air supply being released out the other side.
Today, air purifiers can trap particles as small as 0.1 micron in size – so tiny that you’d need a high-powered microscope to even see them. While fans are still used to move air around, modern purifiers employ a variety of different ionizing and electrostatic technologies to remove not just particles, but also gases and VOCs from the environment.
Clean Air Delivery Rate (CADR)
The Clean Air Deliver Rate – or CADR – is a measurement of the volume of air that a purifier is able to process each minute. For example, an air purifier with a Clean Air Deliver Rate of 350 is able to purify 350 cubic feet of air per minute.
Developed by the Association of Home Appliance Manufacturers, the CADR has become a standard measurement among all domestically sold air cleaners. Each unit is rated with three separate CADR’s – one for tobacco smoke, one for dust particles, and one for pollen.
Using the CADR measurement is a great way to compare the performance of different air cleaners while trying to find one that best fits your spatial and air purification needs. For smaller spaces, a more affordable unit with a low CADR should be sufficient. For living rooms, multi-room areas, and whole-house solutions, you’re going to need to invest in a more powerful unit with a higher CADR – typically at least 350 cu.ft. per minute.
What Exactly Is HEPA Filtration?
When you need high-quality purification, there’s no technology more powerful and efficient than HEPA filtration. HEPA, which stands for “High-Efficiency Particulate Air”, is the standard for residential, commercial, and medical-grade purification, and is a must for anyone seeking relief from allergies, dust, pollen, or pet dander.
The truth is, however, not all HEPA filters are created equal. For the best performance, you want to make sure that you’re purchasing an air purifier with TrueHEPA or PureHEPA technologies. These designations show that the unit is able to remove up to 99.97% of pollutants in your home’s air source down to just 0.3 microns in size – much smaller than you can see with the average microscope.
HEPA filters use a variety of methods for capturing even the smallest particles, including the utilization of a dense mat of glass fibers to block the passage of even the smallest contaminants. Because of their extreme level of purification, HEPA filters are a must for anyone serious about reduce the severity of their allergy symptoms.
Do I Need an Air Purifier?
The short answer is that yes, you do need an air purifier. Because of the poor quality of the stale air present in most homes, just about everyone should be using an air cleaner to protect their health and the health of their family members and pets.
And if you suffer from allergies – especially moderate-to-severe allergies from pollen, dust, or pet dander – you can’t afford not to invest in a quality air purifier. Not only will you experience a huge reduction in your allergy symptoms at home, but you’ll also notice a big improvement to your energy level, focus, and breathing. Basically, breathing in clean, purifier air can make a big difference when you’re used to living in a pollutant-filled home.
