Alternatively, the HERO HS300 can be installed using 8 inch round collars for application requiring ducting.
Included with every system: two 8" round collars, two mounting brackets for wall, installation guide and fasteners.
The HERO HS300 is designed to install directly on the return air plenum of the forced air heating/cooling system. If you choose this type of installation, it is recommended that you run the fan on your forced air system continuously (Fan On mode) to maximize the cleaning effect.
The HERO HS300 is equipped with two specialty types of media air filters that remove pollutants, allergens, odors, and viruses from the air.
The pre-filter with carbon will collect up to 90% particles between 3-10 microns in size, such as pollen, dust, lint, dust mites, pet dander etc. The activated carbon filters out odor-causing particles from the air, such as cooking odors and smoke. The HEPA filter arrests up to 99.97% particles as small as 0.3 microns in size, such as bacteria, legionella, combustion smoke, milled flour, mold spores.
While installed onto the existing 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.
With normal usage, it is recommended to change the pre-filter with carbon (#463046) every 3-6 months and the HEPA filter (463048) once a year. It ensures your ventilation system runs smoothly, and you get the clean indoor air you deserve.

I had Weiss Johnson come and remove two furnaces, redo a whole bunch of ducting, install a new high efficient furnace and also a heat pump. They went above and beyond with helping me. Relocated my hot water heater, moved and repaired a bunch of central vac lines and made everything look beautiful. Not to mention ran to my house at 9pm on a weekend to fix a small issue that could’ve waited. 10/10 from everyone involved.

had Reece and Nick from Weiss- Johnson come and install a new furnace. I have to say that I am extremely pleased with the job they did. They were very professional and pleasant to deal with. Reece is very knowledgeable and did a great job installing the new furnace answering all my questions. Nick did a great job installing the new ventilation pipes. If you are in need of a new furnace these are the guys to get.

First time using the services of Weiss-Johnson because our central ac was not starting. Celine was really nice to speak to and was very upfront about all the costs and services. Elie Haddad was our service person. Very impressed with how thorough and knowledgeable he is and quick diagnosis of the problem we were having with the AC. Will definitely hire Weiss-Johnson again for any AC and furnace related issues. Highly recommended.
