1. What are ionic air purifiers and how do they relate to hepa air filters?
Ionic air purifiers attach an electrical charge to the air that passes through the air purifier. This charge (typically a negative charge) then attracts positively charged particles that are floating in the air. This "weighs down" the particles so that they sink out of the air. Ionic air purifiers are very effective when used in combination with a hepa air filter. Together, a hepa air filter with ionizer is a one-two punch.

2. Do all air purifiers have ionizing air filters included?
No. Many air purifiers rely only on a mechanical filter and do not capitalize on the technology of ionic air cleaners.

3. Will air purifiers remove carbon monoxide or radon if present in a room or house?
The typical room air purifier can remove only particles, not gases. Only extremely expensive, industrial type systems can capture these gases effectively.

4. How will I know that the air purifier is actually cleaning effectively? Will the air smell different?
Often you do not realize how well your air purifier is working until you change the filter and find how filthy it is. Even then, you cannot see the microscopic particles that the filter catches. Some signs that it is working include:

• Less dust on the furniture
• "Clean" smell to the air, especially when using units with additional ionic air purifiers
• Decreased allergens in your home

5. Can I program my Hunter air purifier to come on/shut off at certain times?
Hunter has two models with an auto shutoff feature. This allows you to set the unit to run for 1, 2, 4, or 8 hours before shutting itself off.

6. Is a Hunter air filter included with the air purifier when I initially purchase the unit and how long will the filter last?
All models are shipped with the necessary Hunter air filters. The first filter will typically last from three to six months under continuous use, but it depends upon how "dirty" the environment is and how often the air purifier is used. For example, if your new Hunter unit is a replacement for another unit, then the room is probably cleaner than most. However, if you are putting it in a room that has never had an air purifier, then the first filter will need changing sooner.

7. Can the filters for Hunter air purifiers be manually washed or recycled in any way or do I have to purchase entirely new filters?
Most air purifiers use disposable filters. Hunter units use a combination filter, which is designed to be easily replaced. The top-of-the-line Hunter models have pre-filters to catch the larger particles. This pre-filter can be washed with a hose and used again once it has had time to dry.

8. How do I know when I need to get Hunter air purifier replacement filters?
Hunter models come with either a "check filter light" or a "filter chart" to help you understand when to change the filter. The light comes on after 1,000 hours of use, which is the average time for needing to change the filter. The chart is color-coded to give you an indication of how "dirty" the filter is.

10. How is the appropriate size for indoor air purifiers determined?
CADR air purifier ratings should be used when selecting indoor air purifiers. These scores are generated from independent ratings of room air purifiers tested under simulated real world conditions. The higher the score, the better the unit cleans a room. Hunter model CADR scores and room size guidelines are featured in the air purifier comparisons page.

11. How are the CADR air purifier ratings generated?
The Clean Air Delivery Rate (CADR) score gives the consumer the best indication of performance. The real world testing which leads to the CADR ratings of room air purifiers is approved by the Association of Home Appliance Manufacturers (AHAM) and ANSI (American National Standards Institute). The testing has also been recognized by the FTC as the only valid comparison of performance for room air purifiers. The testing involves filling a room with particles and testing how quickly indoor air purifiers clean the air in the room. There are three tests, using smoke, dust and pollen because each has different properties. Smoke is considered the hardest to clean, and is, therefore, used to establish how large a room a tested unit will clean.
