1 Performance pg. Pollens and spores, which can aggravate allergy symptoms, are usually in the 10-100 micron size range. The visible household dust particles, and nearly all pollen and spore particles, therefore, can be caught and permanently held, very easily, if you can get them to the air cleaner. Continuous air cleaning will be accomplished when your thermostat is set for continuous air circulation. If continuous air cleaning is not required, or desired, you can manually set your control for any time period you desire.
Many thermostats have a switch position for manual fan.
This is why it is important to do household dusting several hours after vacuuming. Where allergy symptoms, which are aggravated by pollens and spores, are a concern, continuous cleaning is strongly encouraged. For pollens and spores which aggravate an allergy condition, your cleaner must be operated continuously when these pollutants are in the environment. The air cleaner can only be effective when air containing the contaminants is drawn through the high efficiency media. The Space-Gard Air Cleaner requires no electrical component service, generates no ozone, and is not affected by relative humidity or temperature.
