Best 20x25x5 Air Filter Buyer's Guide:
Having any filter isn’t what you need, but having the right air filter is all you need. Getting, right?
When you have a bunch of high-end models in front of you, choosing the best one is more than a real-time challenge.
If a filter design inspires you, its cost may be a little higher than your budget. If it’s worth your budget, maybe you’re expecting quite more than that. So there are many things going hand in hand.
What’s the catch?
Just like you try to make the right choices in life, here, you have to make the right choice too. You have to make sure that you end up choosing the best bang for your buck.
How will you do that?
Don’t worry! We’re here with all those things you have to keep in mind before getting into any particular model.
The Filter Type -Most Important!
Do you know what the core of an air filter is? The type of filter used in a cleaner actually determines its efficiency and smartness.
Where the air conditioning, heating, and refrigerating industries are going beyond the levels of human thinking, air filtering engineers had ensured a powerful jerk to its standards and efficiencies.
The perfect depiction is MERV (Minimum Efficiency Reporting Value) that came into play as an integral part of air filters to remove even traces of large and small airborne particles.
Want to know more? Let’s explore its types!
The most common type of filters that are in-use these days are throwaway types -fiberglass. There are thickened layers of fiberglass, reinforced with metal grating, to produce a filter media.
With much more turbulence to airflow, the polyester filter is quite similar to the fiberglass one. However, there’s no doubt in its premium dust-eating ability.
A High-Efficiency Particulate Arrestance filter is the best treatment for all airborne pathogens. It meets DOE standard STD-3020-97 and filters them at a modest scale.
The HEPA filter can sieve even 0.3-micron particles with 99.97% efficiency. The choice is yours!
The Efficiency Matters!
Once you’re done deciding the filter type, next, you have to bring the air change rate (ACH) into consideration. What’s it, by the way?
It’s the frequency of how many times the filter has purified the whole room’s air, most probably in an hour. The greater the air change rate, the greater the efficiency will be.
If you find any model with a 5 or 6 ACH rating, trust me, you’ve got the best thing. With this rating, a filter can purify air every twelve minutes -so there are few chances of inhaling any pathogens.
Does CADR rating really matter?
Here’s a big YES! CADR -Clean Air Delivery Rate lets you determine the quickness of the air filter’s functionality.
It tells you about the cubic feet of air the air filter is purifying within a minute. The higher the CADR ratings, the better is the functionality of the air filter.
Usually, air filters offer you up to a maximum of three CADR numbers for extracting pollen, smoke, and dust.
But wait! If you want to operate it in a capacious room, it better to look for more than three CADR ratings.
An Activated Carbon Filter is Important Too!
Do you know what secret function a carbon filter performs? You’ll be amazed by its odor-absorbing ability when you’ll get a fresh and hygienic environment in your indoors.
The activated carbon layer takes away all the chemicals and harmful gases and intends to prove the real power of what an air filter actually is.
So when you’re looking for the ideal 20x25x5 air filter Merv 13, don’t forget to look for an activated carbon layer in it.
The larger carbon filter accounts for absorbing more chemicals and delivering the purest version of air around you.
Do you like noisy surroundings? Focus on the Decibels!
Air filters come with a built-in fan to get the whole job done, but the fan inside may get noisy sometimes -it’s an undeniable fact.
The noise may get unbearable, especially during peaceful winter nights. So it’s really a thing to consider before you get into any particular model.
Choosing an air filter having up to 50 decibels is ideally safe; it won’t disturb you with its buzzing fans. However, if you choose any model above 50 decibels, be ready for the challenge!
How much can you invest?
The more you invest, the better you get -that’s the common saying and goes well in the case of air filters too. You know what?
The quality of your air filter depends on the amount you’re going to invest in. Most of the market models don’t demand more than $50 for two or three-pcs packs.
However, there are a few luxury exceptions that offer more than this. Once you determine your budget, the task of choosing the best air filter becomes much easier.
Deciding on the budget means narrowing down the choices from dozens to a few.
