What to Know When Buying AC Furnace Filters

AC furnace filters ensure the air pumped is pure and free from debris and dust. Without them, you can suffer significant health problems, including allergies. With the right one, you can improve your air quality and the system’s overall functioning. However, before buying one, there are a few things to consider. 

Here is all you need to know when purchasing furnace air filters.

1. Understand your Needs

Before considering the technical specifications of air filters, you must analyze your requirements and needs. Know where you intend to utilize the air filter—for instance, your living room, bedroom, or kitchen. Depending on the area, you know which air purifier will absorb dust and toxins effectively.

2. Filtration System 

Furnace air purifiers often utilize filters to eliminate contaminants from the air. However, not all air cleansing is done via filters. Some air purifiers use other methods, such as ionizers and UV lights, to clean the air.

Choosing an air filter with suitable filtration technology is vital to improving indoor air quality. Different types of air filters and technologies are available in the market, each with strengths and weaknesses. However, you can get it from Filter King if you want a durable filter to minimize your replacement intervals.

3. Merv Ratings 

MERV (Minimum Efficiency Reporting Value) ratings are a system utilized to rank the effectiveness of air filters. The MERV rating system ranges from 1 to 20, with the highest number indicating an air filter’s effectiveness. However, not all highly rated filters are effective. Therefore, before you make an order, know the MERV number required for your AC to work effectively.

What filter Sizes are Available, and Why is Size Essential 

There are numerous filter sizes available in the market. However, not all products are standard in most homes. Below are some of the popular filter sizes utilized by most homeowners.

  • 20x23x1

These pleated filters are one-inch purifiers with a Merv rating of 8. They effectively eliminate dust mites, pollen, bacteria, and smoke. Additionally, you can use the filter for either residential or commercial purposes.

  • 12x30x1

The 12x30x1 air filter is constructed to fit Ac systems requiring a specific size filter. They are more expensive but have higher filtration efficiency and can trap tiny particles than standard filters. However, they become dirty quickly as they trap more and more particles; thus, you need to replace them frequently.

Why the Right Filter Size is Essential 

  • Cost Savings

By utilizing the appropriate right size of AC filter, you can avoid damage to your AC unit caused by a filter that is too small or too big. This can save you money in the long run on repairs and replacements.

  • Better AC Performance

The perfect filter size allows optimal airflow through your AC system, ensuring it operates at peak performance. This can lead to better cooling and heating throughout your home and a longer lifespan for your AC unit.

Final thoughts
