For allergy sufferers, each season offers its own allergy triggers, such as spring's airborne pollen, summer's hazy smog, autumn's tumbling leaves and winter's home air pollutants. There are a number of ways to remedy allergies, from using nasal spray or oral medicine to constantly washing or steaming your face. Some of these allergy remedies are much more effective than others. However, one of the most important factors in the fight against allergies is making sure your home is as allergy free as possible. While there are expensive projects, such as removing carpets and rugs, there are also much simpler solutions. Using a good air purifier is one of the best solutions for reducing allergens in your home at a reasonable cost.

Air purification systems are effective tools for removing allergens. When looking for the best air purifier for allergies, consider the different technologies used to help eliminate indoor allergens.

HEPA Filters

The first and most important technology to look for in room air purifiers are HEPA filters. HEPA filters are mechanical air filters that trap allergens such as pollen, dust mites, pet dander and even tobacco smoke. They are designed to remove at least 99.97% of particles that are 0.3 microns or larger as air passes through the filter. HEPA filters effectively remove allergens from your room, so for this filter type in the air purifier you choose.


The second technology to look for is an ionization system. Ionizers electromagnetically or electrostatically charge particles as they pass through the system. These charged particles are attracted to plates in the device, effectively removing them from the air. Charged particles that escape the unit will be attracted to neutral charges in your home, including other particles, to form a larger particle that should be more easily caught on the next pass through the filter.

Although ionizers are effective, it is important to note that prolonged exposure to charged particles may be harmful to lungs, especially if you have breathing-related issues. For allergy sufferers, using an ionizer may replace one set of symptoms for another. An effective way to manage both the amount of charged particles and allergens in your home is to only use ionizers when you are out of the house.

UV Lights

The last air purifier technology to consider is the use of UV light bulbs that are meant to eliminate indoor pathogens. UV lights are used in hospitals to purify equipment, which leads many people to believe ultraviolet rays kill microorganisms as they pass through your air filter. However, UV light purification is only effective in large doses, and hospitals limit the amount of airflow that passes around the equipment that is being purified. Because a large amount of air passes through air purifiers relatively quickly, UV light bulbs are largely ineffective at removing allergens from your home. The theory of UV light purification is solid, but particles do not remain in an air purifier long enough to get a proper UV treatment.


The fight against allergies includes medicines, daily routines and home remedies. Some methods to remove allergens from your home are expensive or time consuming, but air purifiers are inexpensive and less time-intensive alternatives that can help reduce allergy symptoms.
