VACUFLO^® Technology for Cleaner Living: If you're looking for ways to create a cleaner, healthier home environment, you're not alone - a recent survey found that 66% of today's buyers want specific features that make their new home healthier. 

A very important aspect of your home is the quality of the air you breathe. Indoor air pollutants like animal dander, dust mites, mold and pollen are a common cause of allergic conditions and other health problems. Using the right vacuum cleaner can significantly reduce exposure to these airborne particles. 

Vacuum systems that use bags or filters recirculate dust, odors and pollutants back into the air. VACUFLO^®'s patented True Cyclonic™ Cleaning Action eliminates the need for bags or filters. Bags and filters become clogged with dust and debris, reducing power and efficiency. VACUFLO^® systems maintain maximum cleaning efficiency with consistent power and airflow. In fact, 96-98% of all dirt swept into the system is deposited into the clear dirt canister. The remaining fine dust particles are exhausted to the outside. No dirt or odors are recirculated into the home. 

VACUFLO^® also provides sustained cleaning power - the ability to maintain maximum cleaning power over time. The very first time you vacuum with a system that has a bag or filter, there will be a measurable decrease in suction power and airflow as dirt and dust begin to accumulate. With VACUFLO^® True Cyclonic™, there are no bags or filters to clog.

GET THE CLEANEST AIR POSSIBLE
For the ultimate cleaning efficiency and healthier air quality in your home, combine a Signal Air Filter with a VACUFLO^® Built-In Central Vacuum System. In tandem, these remarkable cleaning systems will provide the highest and most efficient degree of clean air possible.

SIGNAL AIR FILTERS capture airborne pollutants as small as 5 microns - particles which are too small to see with the naked eye. These micro particles (pet dander, smoke, dust) are irritants that can aggravate your respiratory system. Signal Air Filters eliminate the need for expensive electronic air cleaning systems.

MAXIMUM AIR FLOW - KEY TO EFFICIENT OPERATION
Today's high-efficiency heating and cooling units operate most effectively with maximum air flow. Signal strips the air of 91% of pollen, dust particles and pet dander, without restricting your HVAC system’s air flow. Low air resistance means:

• Homes heat and cool faster
• Low energy consumption
• Heating and cooling systems operate effectively

HOW SIGNAL WORKS
The Signal Air Filter provides layer after layer of protection, removing airborne pollutants while also allowing a high volume of air to pass through the filter. Safe, electrostatic charges in the filter material work to trap and hold the airborne particles. The high volume of air passing through the layers keeps heating and air conditioning equipment operating at optimum performance.

BACTERIA GROWTH IS INHIBITED WITH MICROBAN B
Bacteria and mold can aggravate allergies and respiratory illnesses. Signal Air Filters are manufactured with a permanent anti-bacterial agent Microban B to inhibit the growth of bacteria and mold. Microban B is extruded into the polypropylene layer of the filter, so it never washes off. In fact, every time you wash the filter the anti-bacterial agent is reactivated.

WHISTLES WHEN IT NEEDS TO BE CLEANED
A clean filter is important to the operation and efficiency of your HVAC system. Cleaning every 2 - 3 months will ensure your Signal Air Filter operates at peak efficiency. In case you forget, Signal Air Filters have a built-in whistle to remind you when they need cleaned. The whistle sounds when the filter is 80% clogged. 

Five Steps to Purified Air Dirty air enters filter through polypropylene outer layer, creating a negative charge. Air bounces against foam inner layer and creates a positive charge. First metal grid acts like magnet capturing most of the positively charged dirt particles. The remaining particles pass through the foam layer and collect on the second metal grid. Clean, purified air exits the filter and is recirculated into your home.
