Indoor Air Quality. It's Simple
Exhaust... Ventilate... Filter

The basics:

  • Exhaust odors and excess humidity.
  • Ventilate your house with fresh air to dilute any pollutants.
  • Filter out allergens using a HEPA filter.
  • Use HRV and ERV's to ventilate, while recovering exhaust heat or cool.
  • Have your house checked for radon gas and mitigate with radon fans as required.

COVID-19 has made us all rethink the safety of indoor spaces. Although the scientific research is not complete, consensus is that a large component in viral transmission involves breathing in airborne micro-droplets.

Why Filtration for COVID-19?

  • Masks are not 100% effective
  • People are not 100% effective at masking
  • Microdroplets stay in the air for up to 10 hours

One of our most popular categories in the last couple of years has been inline filter boxes. They range from basic MERV-6 boxes like our house brand IFB series or the S&P FB series to MERV 13/15/16 available in the CFB and SFB series boxes.  Below is a quick comparison between the AirScape and our house brand filter boxes.


Indoor Air Quality Products

HEPA Filtration

HEPA filters can take out the smallest particles from your air. 99.97% effective down to 0.3 microns.

Inline Filter Boxes

Filter boxes fit inline and contain replaceable filters. It's important to filter air and this makes it simple.

Air Inlets & Fresh Air Kits

Through the wall make-up air inlets and fresh air inlet kits. Inlets available in round, rectangular, self-regulating, adjustable, and filtering models.

Medium Efficiency Air Filters

Medium efficiency air filters are great for residential use where you want a good filter without a high pressure drop.

High Efficiency Air Filters

MERV 11 and 13 air filters are used to take out even the smallest particles.

Carbon Air Filters

Carbon air filters filter particles from the air, but the carbon also absorbs odors and volatile organic compounds.

Air Purifiers

Room and large space purifiers that improve indoor air quality (IAQ) safely and efficiently. For cleaning the air, typically via filtration.

Radon Fans

Radon fans remove harmful radon gas before it gets into your house.

Garage Ventilation

Garage (residential) ventilation fans. Control heat and fume buildup using continuous or intermittent ventilation

Active Dampness Control

Remove moisture and radon gas before it enters your house.


Residential and light commercial humidifiers. Ducted and direct space distribution versions.

Heat Recovery HRVs

Heat Recovery Ventilators provide fresh air, while recovering heat from the exhaust air.

Energy Recovery ERVs

Energy Recovery Ventilators provide fresh air, while recovering thermal energy (heat and humidity) from the exhaust air.

Air Exchange Ventilators

Air exchange ventilators pull in fresh air and exhaust stale air. They DO NOT provide energy recovery like HRV or ERV's.

Zoned Exhaust Systems

Zoned central ventilation systems. They reduce the load on heating and cooling systems because they do not ventilate all bathrooms simultaneously - only the one in use.

Pressure (Air) Balancing

Relieve pressure build up in the home by allowing the movement of air from one room to the next. Wall and door air pathways.

Supply Air Ventilators

Fan systems for filtering and distributing incoming fresh air to residences while preventing the unwanted introduction of contaminants from depressurization and infiltration.


Residential and light commercial thermostats for controlling heating and cooling equipment. Standard 24VAC and line voltage (115V) versions.

Airflow Regulators

Airflow Regulators are modulating orifices that automatically regulate airflows in duct systems to constant levels. These can be passive or active (powered with sensors) devices.

Duct Heaters - Electric

Electric duct heaters come complete with electrical safeties. They can be ordered with single, multi-stage, or modulating control.

UVC Lights and Systems

Ultraviolet (UVC or UVGI) sir sanitization technology. Reduce 99.7-9% of airborne pathogens.
