Andres, another customer, had an issue with his custom order:
“I had some filters customized and were received in no time. Unfortunately, I did have an issue with the measurements so I contacted them. They heard me out and were quick to fix it. This had to be one of the best customer services out there. Without a doubt, great quality/value and I'll be ordering from Filter King again.”
Samuel, who left a five-star review, had been struggling with allergies:
“The filters really filter out everything I need them to. No more runny nose, and sore throat in the morning!”
But beyond odd sizes, what about special cases?
Sometimes, the average isn’t good enough. Our MERV 13 filters are ideal for anyone with a newborn baby in their house. Because babies are more susceptible to indoor air pollution. But also, if you have chronic or severe breathing problems, we make filters for you.
This would include:
- Allergies
- Asthma
- COPD
- Emphysema
- Chronic bronchitis
- Lung disease
And anyone in the household who requires the use of an inhaler, oxygen tank, or ventilation machine, would also fall into this category. They are also recommended for people with weakened immune systems who may be affected by airborne pathogens and viruses.

Discount Air Filters Overview
If someone needs or wants a new air or furnace filter, or they want an upgrade to their current filter, then a discount air filter is a smart choice. It is recommended that houses and residential buildings use air filters with a MERV rating of at least 6.
MERV means Minimum Efficiency Reporting Value and refers to how efficient the filter is at trapping pollutants and allergens. If your air filter has a lower rating then it is advisable to upgrade to a cheap air filter for the home that will create a healthier indoor environment.
Features to Look for in Discount Air Filters
Affordability - A cheap air filter should be a good deal. Make sure that the discount is significant enough that purchasing the filter will not have a negative effect on the household budget.
Quality - An air filter with a high MERV rating is recommended, preferably one between 8 and 13. It will catch the allergens and pollutants commonly found in most residential areas.
Reliability - Air filters need to be changed occasionally but they should not need to be changed before their expiration date because they stopped working properly.
Performance Expectations of Discount Air Filters
Just because an air filter is inexpensive, that doesn’t mean that it should offer below par performance. A cheap home air filter should perform according to its MERV rating. If a discount air filter with a MERV rating of 6 lets in pollen or mold then it is not working according to its specifications. If an air filter performs below the level of its rating, then the situation needs to be rectified as soon as possible.
Recommended Discount Air Filter Purchases
The average person - An air filter with a MERV rating of at least 6. Anything below this rating is not as efficient at filtering out everyday particulates, like dust or pollen.
The person with special needs - If you, or someone in the family, has breathing problems or severe allergies, or if you have a newborn child, then air filters with a MERV rating of 8 to 13 are highly recommended. They will filter out most bacteria and virus carrying agents.

Discount Air Filters: Conclusion

Discount Furnace Filters Overview
Just because a discount furnace filter is cheap, that does not mean that it should be cheaply made. A good air filter, regardless of the price, will trap a wide variety of allergens and pollutants, ensuring that the indoor air quality is of a high standard. This is particularly important if there are any allergy sufferers, asthmatics, or newborns in the home.
If you ever have the opportunity to buy a cheap air filter, then you should make sure that it has a MERV rating with a minimum of 8 and a maximum of 13. Anything lower than an 8 will not be as efficient and anything higher than a 13 could reduce the airflow, causing the furnace fan to work harder, which in turn results in a higher energy bill. Therefore, great care should be taken when purchasing a furnace filter no matter the price.
Features to Look For in Discount Furnace Filters

Furnace Filters on Sale
Furnace Filters on Sale Background
Furnace filters are an important part of the home’s HVAC system. You should always try to get the best air filter possible. Filters with a MERV rating between 8 and 11 are best for most homes. They tend to be more expensive, so if you should ever find a furnace filter on sale, then you should purchase one of the better ones.
MERV means Minimum Efficiency Reporting Value and it indicates how efficient the air filter is at trapping particles. Even if a furnace filter with a high MERV rating is not essential, purchasing one if it is on sale is a good investment for any home.
Features to expect in Furnace Filters on Sale
Should one decide to purchase a high MERV-rated furnace filter if it is on sale, then here are some of the allergens and pollutants it will filter out and keep from circulating:
- Household dust
- Pollen
- Dust mites
- Carpet fibers
- Mold spores
- Hair spray
- Exhaust fumes
Furnace filters with MERV ratings of 8 to 11 will prevent all of the above particulates from circulating. Filters with lower ratings, in the 1 to 7 range, will not trap finer particulates like exhaust fumes. Nevertheless, they should be more than adequate for most people.
How Furnace Filters on Sale should Perform
Furnace filters with a MERV rating of 7 or 8 will provide a good balance of cost and efficiency, they will catch 80% to 95% of particles that are larger than 5 microns. This is efficient enough for most households.
However, homes with more sensitive allergy sufferers should opt for furnace filters with MERV ratings of 9 to 11. Those filters are more efficient and will make the home environment more palatable for them. One caveat is that the furnace fan will have to run full time to get the benefit of the filter.
This will end up costing more so that should be taken into account even if the furnace filter is on sale. Residential homes do not need to go any higher than a MERV rating of 11 because anything higher will lower the airflow, causing the air conditioner’s fan to work harder. The end result is a higher utility bill and possibly worse if the fan gets broken and needs to be replaced.

Furnace Filters On Sale Review Outline
Furnace Filters on Sale Overview
One of the first things to consider when buying a furnace filter that is on sale is its MERV rating. MERV means Minimum Efficiency Reporting Value and refers to how well the filter traps harmful particles. MERV ratings go from 1 to 20, with 1 being the least efficient and 20 being the most. The average household needs a furnace filter in the 8 to 13 range.
Filters below that range are not as efficient, while filters above that range have smaller pores that could restrict the airflow of the HVAC system. This could result in the fan having to work harder, which could in turn result i a rise in the owner’s energy bill. Furnace filters in the 8 to 13 range are good enough to trap the majority of pollutants and allergens that can trigger adverse reactions in affected individuals. So, when you have the chance to buy a furnace filter on sale, make certain that it fits the needs of your home.
