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 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.
NOT RECOMMENDED - Electrostatic Air Purifier
An electrostatic air purifier does not use a filter, but rather an internal filtration system, which attracts charged particles. This internal filtration system has to be cleaned regularly, and over time becomes less efficient.
NOT RECOMMENDED - Ionic Ozone Air Purifier
An ionizer charges particles in the air, making it easier for filters and cleaners to trap and can be effective when used in combination with a HEPA style filter. However, when used alone, it is less effective and can produce harmful levels of ozone in the process.
What to Look For
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.
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.
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.
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.

Air Quality Concern
Whether you want to remove allergens, odors, chemicals, smoke, germs and bacteria, or simply desire pure, healthy air to breathe—different technologies may address different needs in your home.
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.
