Why Buy Air Filters From Filter King?

Image

In comparison to fiberglass filters, 20x30x1 pleated air filters are at least 20 times more effective. All Filter King air filters are made in the US.

Image

Filters frames are made out of heat resistant paperboard with horizontal grid supports. Able to withstand temperatures of up to 200° F and resistant to moisture, the paperboard frames do not support microbial growth and outperforms traditional cardboard frames.

Image

Chemical free, electrostatically charged synthetic polyester media is pleated, maximizing the surface area, to capture a high number of airborne particles as small as 0.3 microns with low air flow resistance. To increase durability, the media is supported with a corrosion resistant steel wire.

How Often to Change Your 20x30x1 Air Filter?

Filter King AC & furnace filters aren’t the typical fiberglass filters that need to be replaced every 30 days. Our filters can typically be used for 3 to 5 months before requiring to be changed. Naturally, a variety of things influence filter lifespan.

Some of the factors that influence your filter’s life include outdoor air quality, whether pets are in the home, and how well your HVAC system is maintained.

Your air filter becomes clogged over time by trapped particles, preventing airflow. The efficiency of the HVAC filter declines. Your system must work harder to heat and cool your home. The extra strain on the HVAC system causes higher energy bills. Regular home air filter replacements can prevent expensive system repairs or replacements down the road.

You should change your filter more frequently if you notice:

  • Household dust build-up
  • The air isn’t cooling as is used to
  • There’s more dust near the air vents
  • A dirty filter surface
  • Higher energy bills
  • Burning smells near your HVAC system.

MERV Rating: Which One is Right for You?

The American Society of Heating, Refrigeration, and Air Conditioning (ASHRAE) developed the MERV filter rating system as a consumer standard. MERV stands for Minimum Efficiency Reporting Value. The rating indicates the filtration level. It ensures all filters with the same rating function the same.

The higher the MERV rating, the more effective the filter is at removing different contaminants. That also means the air conditioner has to work harder because there are more particles to block airflow. The key is finding the right balance for your home or business.

MERV rating shouldn’t be confused with a microparticle performance rating (MPR) or filter performance rating (FPR). MPR is a standard 3M developed to rate their filters and the ability to capture particles smaller than 1 micron. FPR is a similar standard, developed by Home Depot, used for brands sold in their stores, including Honeywell. It uses a color-coded number scale from 4-10 that looks similar to MERV.

At Filter King, we offer 20x30x1 filters in MERV 8, MERV 11, and MERV 13. It’s also possible to purchase a carbon MERV 13 filter for odor elimination.

4-6 Rating: Ideal for Industrial Workspaces

Removes pollen, carpet fibers, clothing fibers, lint, some mold spores, hair spray, etc.

Though MERV 4-6 filters are the cheapest option available today, they aren’t the best choice for residential or commercial buildings. They offer the lowest filtration level, making them suitable only for environments that don’t require much filtration.

8-13 Rating: Best for Home Use

Removes pet dander, smog, most mold spores, fine dust, dust mites, common allergens, etc.

The most common and best air filters for home are within this range. They are often found in commercial buildings, too. Which one is the best choice for your home?

Good: MERV 8 Filter

MERV 8 filters are ideal for most homes. They offer sufficient filtration for those without pets, allergies, or asthma.

Better: MERV 11 Filter

One level higher than MERV 8, the MERV 11 is a mid-level filter. It removes more contaminants than the MERV 8, like pet dander. That’s why it’s a good choice for pet owners and people with allergies or mild asthma.

Best: MERV 13 Filter

The MERV 13 filter provides the highest filtration levels. In the average home, it’s often unnecessary. It’s best for those with severe breathing problems caused by asthma, COPD, chronic bronchitis, etc.

14-20 Rating: Best for Hospitals and Labs

Removes bacteria, viruses, smoke, humidifier dust, face powder, sneeze and cough particulate, etc.

Filters within this range are more than a home needs. Because HVAC systems have to remove so much more from the air, it often translates to higher energy bills. These are only needed in environments where airborne particles are potentially harmful.

FAQs: Common Questions

Below are a few frequently asked questions about our 20x30x1 air filter.

When Should I Change an Air Filter?

In most cases, Filter King air filters will last from three to five months. To ensure you always have a clean air filter when you need it, our filter subscription service sends filters on your desired schedule.

What MERV Rating Filter Should I Use?

The best filter we offer is the Titanium MERV 13 20x30x1 filter, but this is likely too much for the average home. It’s not necessary unless someone in your home has severe breathing problems. Those without pets or health conditions can get by with a MERV 8 filter. Those with mild allergies or asthma can work with a MERV 11.

Do You Warranty Your Filters?

Our standard filters can be returned within 30 days of purchase. This policy doesn’t apply to custom filters.

Do You Offer Bulk Discounts?

Yes, we offer bulk discounts on all our standard filters, including the 20x30x1 air filter. The more you order, the more you save! You can order anywhere from 1-6 or 12 at one time. Orders of two or more qualify for free shipping within the lower 48.

How Long Does Shipment Take?
