While installed onto the return duct plenum, the HERO® HS300 does not restrict the HVAC system's airflow thanks to a built-in fan and bypass technology. Up to 300 cfm of air is drawn from the return air duct, filtered, and returned upstream.

Whether integrated into the whole-house system by way of the HERO® HS300, or in the spaces that need it most with the PHS300, the HEPA filtration system has a comprehensive 3-stage filtration process.

Inspired by air filtration systems used in industrial clean rooms and surgery rooms in hospitals, we put our Portable HEPA Filtration System (PHS300) to the test. It blew us away!

Capture particles as small as 0.3 microns at 99.97% efficiency rate. This includes household allergens like dust mites, pollen, bacteria, mold spores as well as combustion smoke, and milled flour.

If the light turns yellow or red while you are established in the intersection, watch for traffic slowing down to stop and complete your turn when it’s safe. Always be alert to drivers attempting to race an amber light. (If you are not already established in the intersection, you must not attempt the left turn when the light changes from green.)

Left turns are more dangerous than right turns because of oncoming traffic. Different types of streets require different left turn procedures. Only make a left turn when it’s legal and safe.

HERO® HS300 is designed to be installed directly on the return air plenum of the HVAC system. Alternatively, it can be installed using 8" round collars for applications requiring ducting. The portable PHS300 can be placed in dedicated areas where air cleaning is needed.

When it’s safe, move ahead to just before the centre of the intersection and just to the right of the directional oncoming line.

If you have stopped at a red light, when the light turns green, you must move into the intersection if it’s safe. Before moving ahead, you must check:

When approaching the intersection, check for signs that may prohibit or restrict turns. Before making a left turn, enter the proper lane well before the intersection.

Complete this turn the same as any other turn except when two lanes are allowed to turn left at the same time. The vehicle closest to the median must complete the turn and stay in the lane closest to the median on the street being turned onto. The vehicle second from the median must turn into the second lane from the median on the street being turned onto. When turning with vehicles beside you that are also turning, watch for vehicles that may not stay in their own lane and be prepared to avoid them.
