Why Buy Air Filters From Filter King?


In comparison to fiberglass filters, 30x30x1 pleated air filters are at least 20 times more effective. All Filter King air filters are made in the US.


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.


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 30x30x1 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.

30x30x1 Air Filters

AC Furnace Air Filter 30x30x1-Inches

Filter King 30x30x1 size air filters help clean air in residential builds, such as homes and apartments. This model is a grade of high quality, and it can help you reduce allergies and improve your comfort indoors. Our filters will trap dust and other contaminants in the air so that clean air will enter your home. But it’s important to consider when to maintain or replace your air filters.

The tight mesh weaving in your air filters is ergonomically designed to allow airflow to pass through while harmful irritants stay behind. The fresh air that enters cycles through your home and makes it easier to breathe inside. Indoor air quality rises, but the air filters become dirtier in the process.

International shipping to Canada and Hawaii will involve your order being placed on hold until you receive a freight cost quote and pay. You can return most sizes within 30 days of purchase, but custom sized filters are ineligible for return.

MERV Rating: Which Should You Use?

The Minimum Efficiency Reporting Value (MERV) rating shows your air filter’s capabilities regarding what they can block from entering your home. Higher MERV ratings can block microscopic contaminants mere microns in length, while lower ratings filter dirt and dust.

Our air filters 30x30x1 come in MERV ratings 8, 11, and 13. You can upgrade the MERV 13 to titanium or opt for one designed to eliminate odors.

4-6 Rating: Recommended for Industrial Workplaces

Removes: Pollen, dust mites, carpet and clothing fibers, cockroach waste, cement dust, hairspray, powders, etc.

We do not recommend MERV ratings 4-6 for homes, but you can use them in environments needing little filtration, industrial workplaces, or paint booth inlets. These filters come in washable and disposable forms, and they are the cheapest options. Once you get to the 5-6 range, you’ll find disposable pleated filters that trap particles in their folds.

8-13 Rating: Recommended for Home Use

Removes: Lead dust, Legionella bacteria, milled flour, welding fumes, dust from humidifiers and nebulizers, coal exhaust, smog.

The filters most recommended for home use are filters between 8-13 MERV rating. These work well in residential and commercial buildings. Depending on your home environment quality, you may require different ratings.

  • Good: MERV 8 Filter
  • At a minimum, MERV 8 filter can be appropriate for most residential homes. Those living in a home with no one struggling from respiratory illnesses can try out a MERV 8.

  • Better: MERV 11 Filter
  • MERV 11 filter is a mid-level filter, a step higher than MERV 8, and can remove a much higher percentage of contaminants including pet dander and allergens. We recommend MERV 11 to those with pets or who have mild allergies or asthma.

  • Best: MERV 13 Filte
  • Lastly, those with more severe breathing problems like severe allergy sufferers, COPD, asthma, chronic bronchitis, emphysema, or lung disease, or those with an immunocompromised or newborn individual in their house would benefit from a MERV 13 air filter.

14 - 20 Rating: Recommended for Hospitals & Laboratories

Removes: Bacteria and viruses, sneeze and coughing droplets auto emissions and fumes, tobacco smoke, insecticide dust, face powder, microns, radon, carbon dust, salt, combustion emissions, dust lint, etc.

MERV 14-20 filters are typically bag or box filers. People use them in steel mills, chemical production facilities, food manufacturers, power plants, and operating rooms, pharmaceutical manufacturing facilities. You are unlikely to find one that’s small or affordable enough to fit in your home, and the quality is unnecessary for most situations.

FAQs: Common Questions

Below are a few commonly asked questions about our 30x30x1 air filter.

When Should I Change an Air Filter?

Most residential air filters last three to five months before needing replacement. You will need to change your air filter when you notice the air quality worsening. However, you can stay on the safe side by opting for our filter delivery subscription to receive a clean filter on a schedule, ensuring clean air year-round.

What MERV Rating Filter Should I Pick?

The best option we offer is the Titanium MERV 13 30x30x1 filter. However, this rating may be overkill for your household. If your family lacks any breathing problems, you can get away with a MERV 8. Those with mild issues could use a MERV 11, and those with more severe health conditions should get a MERV 13.
