Did You Know?

  • A typical gram of household dust contains millions of bacteria.
  • Poor air quality is linked to respiratory infections, heart disease, and even developmental issues in children.
  • Taking control of your air quality is one of the best decisions you can make for your home.







Air will take the path of least resistance, every time
To make sure that all the air and pollutants go through your furnace filter and not around it, your new filter features our patented Leak-Guard Seal. When your air conditioner or furnace turns on, the difference in pressure causes an air-tight seal. No bypass means you're filtering 100% of the air. That means the harmful particles are trapped in the air filter, rather than in the lungs of you and your family.

How do Activated Carbon filters remove odors?
Activated Carbon filters have the ability to capture gas molecules and hold them. The Activated Carbon filter surface is made up of millions of tiny pores, the gas and odors fall into these pores and are trapped there until the air filter is disposed of. The carbon filter has a flattened surface area of a football field!

How do Zeolite air filters remove odors?
A three-dimensional, micro-porous natural earth mineral, thermally bonded to polyester. Zeolite has the ability to remove Volatile Organic Compounds (V.O.C.) and gases.They are trapped in the void porous cavities in the filter. It is especially useful in removing Ammonia and ammonium compound odors such as pet odors and urine odors.

Make Your Home An Oasis
Household dust contains up to 1,000 different species of microbes, with tens of millions of individual bacterial cells in each gram.

 

With recent scientific research on how the quality of our air impacts our health and well-being, we’ve learned that it can cause illnesses such as respiratory infections, increased blood pressure, heart disease, and cancer and that it is linked to autism in children.


Not protecting the quality of the air you breathe, is no longer an option.

Understanding Air Filters: Furnace, AC, and HVAC Filters Explained

1. Identical Functions, Different Names:

  • HVAC, Furnace, and AC Filters: They're all the same, just called differently based on regional preferences. In the north, they might be known as furnace filters, and in the south, as AC filters. Essentially, they are all air filters.

2. Purpose of Air Filters:

  • Functionality: Air filters do more than you might think. They can reduce a wide range of airborne materials including pollen, smoke, pet dander, bacteria, dust, mold, dust mites, and more.
  • Customization: You can select the level of filtration needed for your home.

3. Air Filter Rating Systems:

  • MERV Ratings: This industry-standard measures filtration efficiency. Higher MERV numbers indicate better filtration. For example, MERV 13 filters trap household dust, pollen, pet dander, outdoor pollution, mold spores, microscopic allergens, bacteria, most tobacco smoke, and even sneeze bacteria and virus carriers.

4. Types of Air Filter Materials:

  • Carbon Filters: Good for removing odors, made of porous material.
  • Fiberglass Filters: Capture large particles, durable but low in efficiency.
  • Electrostatic Filters: Excellent at filtering most contaminants, available in disposable or reusable forms. They have a charged surface to capture a wide range of particle sizes.
  • HEPA Filters: Ideal for hospitals and those with sensitive respiratory systems. Removes at least 99.97% of very small (0.3 microns) airborne particles.

5. Benefits of Furnace Filters:

  • Improves Air Quality: Filters out allergens and bacteria, providing clean air.
  • Protects HVAC Systems: Prevents dust buildup in the system.
  • Energy Efficiency: Regular replacement of filters can reduce energy bills, as the HVAC system requires less effort to circulate air.

6. Variety of Sizes:

  • No Standard Size: Over 150,000 sizes available.
  • Popular Sizes: Includes 16x25x1, 20x20x1, 20x25x1, and 17.5x23.5x1
