Frequently Asked Questions

Q: What is a MERV rating?
A:  Most filters are labeled with a MERV (Minimum Efficiency Reporting Value) rating number, which measures a filter's ability to trap particles ranging in size from 3.0 microns to 10.0 microns. Residential filters commonly have MERV ratings of 1-11. The higher the MERV rating, the more efficient the filter is, and the more particles it can filter. A MERV rating of 11 means the filter is 85% minimum efficient at capturing particles, sized 3.0-10.0 microns.
Q: How can I improve the quality of the air inside my home?
A: The most effective way to improve your indoor air quality can be achieved by reducing the amount of pollutants in the air. Today, most people spend 90 percent of their time indoors, and 50 percent of all illnesses are either caused by or aggravated by poor indoor air quality (IAQ). According to studies conducted by the U.S. Environmental Protection Agency, exposure to air pollutants can be 100 times higher indoors than outdoors. Frequent dusting and vacuuming will reduce the amount of dust and dust mites present in your home. However, not all airborne particles can be eliminated. Filtration devices can eliminate particles that are too small to be captured by a vacuum. Some filtration devices include UV light units, air filters, energy recovery ventilators (ERVs) and heat recovery ventilators (HRVs), and electronic air cleaners.
Q: My filter is an odd size is that unusual? What is a Nominal Size?
A:  In general, all standard filter sizes are stated according to their nominal size and not their actual size.  The nominal size represents the size of your filter rack.  The actual size represents the size your filter should be to fit inside your filter rack.  Typically, your filter is 1/4" to 1/2" smaller than your filter rack.  The nominal and actual size can be found on the side of your air filter.
Q: How does a UV Light Unit work?
A: UV light units help decompose contaminants such as bacteria, chemicals, dust mites, animal dander, cat saliva, and mold through a process called photolysis oxidation. When the UV lights are installed in the ductwork of your central air and heat system, they can eliminate most of the organisms in the treated area.
Q: Is an air filter enough?
A: The efficiency of the air filter should be a top consideration. Efficiency is measured in terms of the particle size an air filter can capture. The higher the efficiency, the more effective it will be. Look for the filter’s MERV (Minimum Efficiency Reporting Value) number, a new industry standard that rates filters based on their performance. Residential filters typically have a MERV range of 1-8. Higher ratings indicate filters that are more efficient.
Q: What other methods can be used to purify my home’s air?
A: Activated carbon and micro biocide treated filters can also purify your home’s air. Both the carbon and the micro biocide treated filters remove odor and kill bacteria, but the carbon filters are more adept at removing odor, and the micro biocide filters trap bacteria as the air is pulled through, which inhibits biological contaminants from growing.
Q: How can I increase the amount of fresh air in my home?

A: The energy recovery ventilators (ERV) and heat recovery ventilator (HRV) bring fresh air into the home and exhaust stale air out. The HRV conserves energy from indoor conditioned air, and transfers it to the outdoor air as it is brought into the home to provide ventilation. The ERV does the same thing, but it also maintains the desired humidity levels to keep the house comfortable.

Electronic air cleaners clean the air by taking recirculated air and passing it through a pre-filter that traps the large pollutants. Then, ionizing wires give a positive electrical charge to remaining particles. The particles are collected by a negatively charged collecting section. Pollutants pass through an optional carbon filter that absorbs unwanted odors.

Q: What size product is right for me?
A: There are several approaches to finding the proper sized product for your home. First you need to know the sqaure footage of your home and second you need to know the size or the equipment that you will be installing your product to. Once you have this information the owners manuel/install guide will lead you from there.
