Where to Buy Air Filters?

When you need to buy air filters for your home, quality is more important than you may realize. Air filters have an important place in the ventilation system that keeps indoor air quality clean and fresh smelling. If you purchase a low quality air filter from a provider who is not focused on your satisfaction, then you may end up with air quality issues. Filter King is able to provide top quality air filters for your home at affordable prices and qualities that benefit you.

Top Quality Air Filters for the Home

Our models of filters tailor made for your air system and made to protect the air you breathe. The air filters you use will act as a buffer between your home and any floating airborne contaminants, irritants, and allergens. In areas that have higher levels of pollutants or allergens, air filters prevent their entrance into an air system.

The air filters cleanse the airflow passing through and only leave the clean air to enter your home. The clean airflow delivers the fresh air and ensures that the temperature in your home are what you want it to be. However, the air filters in your home are subject to several factors that determine how long the filters last and the quality of the air they leave behind.

MERV Ratings

MERV, or Minimum Efficiency Reporting Value, is the rating system that expresses filter quality. Air filters consist of tightly weaved mesh that traps or absorbs the airborne issues trying to enter your home. The weave’s tightness determines how highly it ranks on the MERV scale, and the particles is able to block.

Air filters with higher MERV ratings capture more irritants, which causes them to lose effectiveness faster. Higher rated filters are also detrimental to airflow, the highest rated filters are only sold to industrial and commercial buildings. The best air filters for your home have a balanced MERV rating to provide you with filters that provide even amounts of protection and lasting power.

Filter King Provides Top Quality Filters

Our filters come in two different models that provide the home with the protection that it needs. The Filter King standard model filter provides protection against the basic outdoor airborne irritants trying to make their way into your home. Our standard filter is more affordable and ranks as an 8 on the MERV scale.

The Filter King premium filter is higher rated and the recommended filter for your home. The air filters is rated as an 11 on the MERV scale and is capable of blocking out even smaller airborne particles. You can buy the premium filter to protect against:

  • Dust
  • Dust Mites
  • Pollen
  • Pet Dander
  • Bacteria
  • Viruses
  • Smoke
  • Mold

Quality air filters provide your home with protection against airborne problems that could make your home uncomfortable or unsafe. The air filters keep contaminants that could cause breathing problems or allergic reactions outside. But, high quality air filters eventually lose their effectiveness and need replacement.

Have New Filters Brought to You Monthly

You are going to need new filters brought to your home in order to avoid dirty, old filters from causing complications. When your filters become dirty, then that affects the airflow trying to come through. The air system needs to use extra energy in order to keep the airflow moving which causes electricity usage to rise. Your bills will reflect the additional energy needed and your home will suffer from stagnant, dry air without proper airflow.

When you need to replace your air filter, then the process can be a burden on your schedule. For a process that only requires a few minutes of your time, purchasing the air filter should be the easiest part. Filter King makes a simple process even easier by having new filters delivered right to your door. The delivery schedule and filter quality are modifiable to match your budget and you can have fresh, new filters brought to your home as often as by the month.

Quality Air Filters Review

Quality Air Filters Overview

A quality air filter should have a MERV rating of 8 to 13 since filters in that rating range provide the best indoor air quality without restricting the airflow of the HVAC system. MERV stands for Minimum Efficiency Reporting Value and is a measurement of how well the filter removes harmful particulates from the air. The ratings go from 1 to 20 with the higher rated filters providing the best filtration.

You should not get filters with a rating of more than 13 since anything higher will restrict the airflow of the HVAC system. Filters in the 8 to 13 range are good enough for most homes and will provide the IAQ that will keep all the occupants satisfied and breathing freely.

Key Features of Quality Air Filters

Air filters with MERV ratings in the 8 to 13 range should efficiently filter out the following particulates:

  • MERV 8 - Pollen
  • MERV 8 - Dust
  • MERV 8 - Dust mites
  • MERV 8 - Pet dander
  • MERV 8 to 11 - Mold spores
  • MERV 8 to 11 - Exhaust fumes
  • MERV 8 to 13 - Tobacco smoke
  • MERV 8 to 13 - Smoke
  • MERV 8 to 13 - Some bacteria
  • MERV 8 to 13 - Droplet nuclei (droplets from a cough or a sneeze)

How Quality Air Filters Should Perform

A high quality air filter will clear the air of allergens and pollutants that can harm vulnerable individuals and irritate everyone else. They are also effective in preventing the spread of airborne infections since they can trap the droplets from coughs and sneezes. Quality air filters are good for household cleanliness in general since they can trap a large amount of dust.

They should not have a negative effect on the home’s energy bill since air filters in the 8 to 13 MERV range will not restrict the airflow of the HVAC system. A restricted airflow will put a strain on the fan because it will have to work harder and run longer to push air through the pores of the filter. That extra effort will result in increased energy costs.

Who Needs to Buy Quality Air Filters

  • Anyone who has severe allergies
  • Homeowners who have asthmatic people living with them
  • Immunocompromised people
  • Parents of newborns because they will need an environment with a high IAQ

Quality Air Filters Review: Conclusion

A quality air filter is a good investment for any home, not just homes that have people vulnerable to airborne allergens and pollutants. Everyone can benefit from a high IAQ and a reduced risk of airborne infection. Quality air filters may be more expensive but they are worth the cost because, unlike lesser air filters, they never need to be replaced.

A quality air filter should not have a negative effect on the energy bill since the fan of the HVAC will not have to work hard to push air through the filter. Overall, a quality air filter is great for the home, the home’s IAQ, and everyone inside it.

Air Filters for Air Conditioners

The air inside your home is not automatically clean by nature, it has to go through filtration first to become clean. An air filter traps dirt and debris coming through a ventilation system before they have the chance to enter your home. Filters trap and absorb plenty of airborne irritants and allergens over time, but they do not last forever. A filter’s use, environment, and effectiveness all help dictate how often your filters will need replacing.

MERV Ratings

MERV, or Minimum Efficiency Reporting Value, ratings are among the first things you should check before buying filters of any kind. Air filters consist of tight weaving, the closer the strands, the higher the ratings and the smaller the particles it is able to absorb. The average MERV Rating for home air systems falls between 8 and 12. Higher rated filters are usually reserved for industrial of commercial buildings. Filter King offers standard and premium filters MERV rated at 8 and 11, respectively, in a variety of sizes to suit most air systems.

A/C Air Filters

The basic A/C air filters are in a ventilation system to keep the airflow coming through clear of harmful, microscopic intruders. Your air filters last only a certain amount of time, usually depending on the MERV rating, before requiring replacement. When your home suffers from dirty filters, the results are consequences to both billing and airflow.

When a filter is dirty, then that causes problems with airflow through a ventilation system. The air cannot easily make it through the blocked-up filter so the system works to compensate. The ventilation system uses up extra electricity to keep the air flow going and the result is a spike in energy use. Unless you maintain your ac air filters, the energy bills start to increase and quickly stack up over time.

A/C Furnace Filters

The traditional model of furnace works by pumping air inside, heating it to the right temperature, and then re-releasing the air. A blower fan pushes the air through this process, and the AC furnace filter protects the blower fan. An AC furnace filter will prevent certain airborne particles from traveling through a blower fan and ending up in the ventilation system. A furnace filter must be periodically replaced like AC air filters, as well. Airflow issues with a furnace may cause temperature fluctuations throughout your home.

Central Air Conditioning Air Filters

A central AC air conditioning unit requires a large amount of space and a large filter to work effectively. The unit pumps in air from the outside before re-distributing it throughout your home, but not before filtering the air first. A central air conditioning air filter is able to prevent entrance to allergens and pollutants such as:

  • Dust
  • Dust Mites
  • Pet Dander
  • Smoke
  • Pollen
  • Mold
  • Bacteria
  • Viruses

Once the central air conditioning air filters are in place they can immediately begin protecting your home. Old central air filters may are disposable by either trashing them or recycling them.

Disposing of Old Filters

When you need to replace your old filters, the process is easy to learn and quick to do. You can locate the air filters using your owner's manual, and from there, remove it. Afterward’s, you can place a fresh, new filter in place so that the airflow is not disrupted or unfiltered. The old disposable filters need careful handling or the trapped dirt and debris may be re-released back into the air.

Find Air Filters That Suit Your Needs

The air filters you need depend on the type of ventilation system you have in your home. Your home may be in need of multiple filters of different sizes. You can order the amount of filters you need at the quality you want in the sizes best suited to your air systems. You may even use our subscription service where we deliver brand new filters to your home as often as on a monthly basis.

Heating and Air Filters

The average home depends on air filters to keep the incoming air fresh, clean and free of airborne issues. As air is pumped inside, it passes through the air filters, and any accompanying particles become trapped or absorbed in the mesh weaving. The heating and air filters provide a protective layer that blocks any particles it can, but will eventually need replacement. An unfiltered air system lacks protection for your system against airborne irritants and allergens.

Filter Protection for an Air System

Air filters allow the airflow traveling through to pass, but trap and absorb passing particles to raise indoor air quality. Home ventilation or heating systems without the protection of a filter is unable to stop any number of pollutants or allergens. Unfiltered air is uncomfortable, and possibly even dangerous. Residents who have breathing problems or allergies are at risk of having their conditions triggered while breathing in low quality air.

The air filters in your home keep air quality from dipping, but in doing so, they become dirty themselves. Heating and air filters will inevitably become covered in dirt and debris over time to a point where their mesh weaving gets clogged. An air filter becomes so covered in captured particles that it can’t hold anymore. A dirty filter also creates a clog in your air system, an obstacle that causes disruptive complications throughout your home.

Air systems cannot push airflow through dirty filters, which leads to your home smelling dry and stagnant. Your home that lacks fresh air is also harmful, causing a possible development of breathing problems for residents. The air system will also need to use more electricity in an attempt to bypass the blockage, causing a rise in energy billing. You will be able to avoid air filter issues by regularly maintaining the system.

Air Filter Maintenance

Heating and air filters need consistent maintenance to prevent particle buildup from occurring. You should check the air filters before any complications start occurring within your home. The filter location is in the owner's manual, from there you will be able to see if it needs replacing. You will also be able to make an educated guess on how long your filter is able to last based on the environment around your home and its level of efficiency.

The air coming in and out of your home plays a large role in dictating how long an air filter is going to last. Environmental variables include dry areas full of sand or dust, humid areas with mold, homes for smokes, homes with pets, and even homes with fans. Some areas dirty filters faster than others, with the filter's efficiency deciding how many particles it is able to contain.

MERV Ratings for Air Filters

Air Filters rank on the MERV, or Minimum Efficiency Reporting Value, system dictating their efficiency. Higher MERV rated filters can absorb smaller particles and keep the passing airflow even cleaner. Your average heating and air system for your home works best when using a moderately-rated filter. If a filter’s MERV rating is too high, then there will be issues with airflow that tax a system and raise energy bills.
