Having a hard time figuring out which air filter to buy? When purchasing an air filter, there are numerous factors, including price and quality. A good quality air filter has perks such as removing dust from the air and preventing allergies, but it also has downsides, such as higher costs.

If you’re having a hard time deciding whether you prefer a cheap or an expensive HVAC filter, Home Alliance is here to assist you with the perks and inconveniences of cheap and pricey air filters.


It’s a no-brainer that the expensive HVAC filter will have a higher quality filter. An expensive air filter will likely have a sturdier frame and better air quality than cheap ones. These air filters last longer than cheaper ones and filter more dust and contaminants.

In contrast, just because cheap air filters are – well, cheap – doesn’t mean they are of poor quality. Cheap HVAC filters can work as well as expensive filters. Besides a sturdier frame, there isn’t much difference between the two.

Air quality

Although there isn’t much difference in the quality of the frame between the cheap and expensive air filters, air quality is a different topic. Expensive air filters make it harder for micro allergens to pass through the filter, which is essential for people with serious allergy issues.

However, if you don’t have anyone in your household with said issues, it is better to buy a cheap air filter and change it monthly—depending on the advice of your professional HVAC technician.


Since expensive air filters make it harder for micro allergens to pass through, it also makes the airflow harder. This makes your HVAC consume more energy leading to a higher electricity bill. Cheaper air filters, on the other hand, need to be replaced every once in a while, depending on your living situation. This can add up over the years, making it seem more expensive than buying a great price-productive ratio filter.

It depends on your circumstances, whether you have serious allergies, pets, etc. So which one will you buy? Will you go big or go cheap?
