  • We spend up to 90 percent of our time indoors, breathing air the EPA warns to be 2 to 5x more polluted than outdoor air. Many are unaware the symptoms they experience—allergies, sinus headaches, trouble sleeping or asthma attacks—can be attributed to poor indoor air quality.

    An air purifier removes allergens and impurities from the air. Many Alen HEPA Air Purifier owners say it takes less than 48 hours to see and feel a difference.

    Air Purifier Technologies

    RECOMMENDED - HEPA Air Purifier
    High-Efficiency Particulate Air (HEPA) air purifiers utilize the most effective filter technology on the market. Only HEPA air purifiers can remove a significant amount of allergens and pollutants from the air—up to 99% of airborne particles as small as 0.3 microns in size. All Alen Air Purifiers use HEPA filtration technology. Many of our filters also include additional technologies to address multiple concerns.

    NOT RECOMMENDED - Electrostatic Air Purifier
    An electrostatic air purifier does not use a filter, but rather an ionizer and oppositely charged metal plate to create its filtration system. Charged particles get attracted to the metal plates, which have to be cleaned frequently to maintain performance. Eventually, the plates need to be replaced. Learn More

    NOT RECOMMENDED - Ozone Generators
    Many people mistakenly purchase Ozone generators that are marketed as air purifiers. Ozone generators are very effective at removing odors and they produce a fresh scent in the air. (This scent is the smell of ozone.) However, despite the fresh smell, Ozone is extremely irritating to the eyes and lungs. Ozone generators sold as air purifiers are banned in the state of California for this reason. Learn More 

    Where to start?

    Room Coverage Area
    Compare your home's room sizes with listed coverage areas along with air exchange frequency. One full air exchange indicates all the air within a specified coverage area has passed through the air purifier. Consider an air purifier that covers a larger area than your room size for more frequent air exchanges, ensuring optimal circulation of pure air.

    Value and Price
    Expect to pay $300-700 for an air purifier that will last. Many customers report having gone through three or four cheaper air purifiers before finally settling on a quality unit. A quality air purifier is an investment, one where you pay for what you get.

    Other Important Things to Consider

    Warranty - An effective air purifier can be an investment. Once you experience the benefits of a high performance air purifier, you won't want to breathe without it. Consider the warranties available—the shorter the warranty, the less amount of time it will last.

    Trusted Customer Service - Find a brand with a history of good customer service and a direct relationship with customers. Read through product reviews or see what kind of information the company publishes related to indoor air quality.

    Performance - When looking for an air quality solution, you want to know the investment you make is going to solve the problem. Look for an air purifier that guarantees performance with an opportunity to try the product in your home, risk free.

    Filter Availability - There is nothing more frustrating than not being able to find replacement filters or receive service. You want to purchase with a lasting brand, one that will be around when your air purifier requires a filter replacement or you need customer service assistance.
