Standard Fiberglass 1"
MERV 11 or MERV 16
MERV stands for Minimum efficiency reporting value. It is a measurement scale designed by ASHRAE, the American Society of Heating, Refrigerating and Air-Conditioning Engineers to rate the effectiveness of air filters.
Please call us today at 1-800-886-2188 and ask for an Indoor Air Quality Evaluation. We will come to your home or business, evaluate your ductwork, fans, systems, and most importantly your individual wants and needs. We will then offer you several options and answer all of your questions. We will not charge you anything for this service, and you will not be obligated to us in any way.
All of the answers listed below are averages. Some of the variables that will change these are:
1. Animals (dogs, cats, etc.) in the rooms being served.
2. The air tightness of the building.
3. How often doors or windows are open.
4. The cleanliness of the outdoor environment (ie: feedlot, near a dirt road, candles being used, etc.)
5. The amount of movement or use (People with many children running around need more frequent filter changes than people who are more sedentary)
1" MERV 4 Filters 2 times per year
1" Pleated Filters Every 2 Months
4" MERV 8-16 filters Every 6 Months
6" MERV 8-16 filters Annually
Please monitor you situation carefully until you learn the frequency needed. If you are in doubt, simply bring your dirty filter to one of our offices, let us look at it and we will make a more informed recommendation specifically for you.
Most air filters come with an arrow showing the direction of flow. Generally the air is flowing towards the furnace blower motor. If you are unsure, please call us. You can even text us a picture of your system and we will tell you the direction of flow.
We offer dozens of types and hundreds of sizes of AIR FILTRATION SYSTEMS. Proper filtration is often overlooked by home and business owners, and yet often causes more discomfort and loss of productivity than improper heating and air conditioning
equipment. The systems we have found best please our customers are Pleated filters incorporated into the HVAC system. We prefer systems with a MERV RATING above 8. The standard fiberglass filters many homes and businesses use are a MERV 4.
One, often overlooked is the amount of air moved across the filter. Many people attempt to clean up the air by using "FREE STANDING FILTERS" purchased at department stores or on TV. While some of these are scams, many use good technologies. The problem with them is that they can only filter the air that moves across the filter itself. Many FREE STANDING FILTERS MOVE only about 1or 200 CFM (Cubic Feet per Minute) while most HVAC systems move between 1200 and 2000 CFM. Very simply, by moving more air through them, we are able to clean more air faster and more effectively. Putting a good filter in your HVAC system will provide much greater results.
If Air Quality is important to you, you should be using at lest a MERV11 filter. Please take time to read about MERV RATINGS and what they mean to you. While the MERV RATING is a good indication of how well a filter stops undesirable particles from passing through your filter, it does not tell you anything about how much air it will pass, or how often the filter has to be changed. While there are many more factors, a good indication is how thick the filter is. Many of our MERV 8-16 filters are between 4" and 8" thick. They are the PLEATED TYPE which allows them to collect huge volumes of particulate between the folds, while still passing the air the rest of your system needs. Filters that are only 1" thick are either very inefficient or they have to be changed very often.
We recommend that our customers run their fans on continuous. It doesn't do any good to have the best filter made, if it is sitting in the basement with no air being moved across it. I know, you're thinking, "But that will cost me a lot to run my fan continuous." Please take time to read about our ECM FAN MOTORS that operate for a fraction what your old fan does.
Get the air to the right place. Proper placement of Return air and Supply vents can have a major impact on the quality of your indoor air.
Keeping it clean or changed. When your filter gets dirty, it begins to restrict the airflow. This can be disastrous to your equipment, decrease your energy efficiency, and cause the filter to tear or collapse, allowing all of the undesirable pollens, spores, dust, and other pollutants it has been saving you from, right back into your air space all at one time.
The most important thing you need is SOMEONE YOU CAN TRUST, who is knowledgeable of the products, engineering, application, and installation of the options available that can help you.
