Q1. What is the Best Furnace Filter?
A1. All the good furnace filters can filter the air and make the entire environment health-friendly. To enter the race of best-rated furnace filters, your furnace filter must have the following qualities when you buy them:
MERV is the Minimum Efficiency Reporting Value. This is a reliable measurement developed by ASHRAE (American Society of Heating, Refrigerating, and Air Conditioning Engineers). The higher MERV rate provides better filtration. The best MERV is higher than 10.
The best Micro-Particle Performance aka MPR for a furnace filter lies between 1500 to 1900.
To trap particles and bacteria, a High-Efficiency Particulate Air (HEPA) is important in an air filter. Such a HEPA furnace filter reviews the quality of your air indoors to clean it effectively.
Always check the furnace filter ratings. The higher Filter Performance Rating, i.e., FPR the finer the performance.
Q2. What is the most common size furnace filter?
A2. Furnace filters come in a wide range of common and standard sizes with different brand names and types. The most common furnace filters are about 1 to 6 inches in depth. And common size are:
10 X 20, 12 X 12, 16 X 24, 18 X 30,14 X 20, 14 X 24, 16 X 25, 18 X 20, 20 X 25, 12 X 30, 15 X 20, 18 X 24, 20 X 30, 12 X 36, 20 X 20, 12 X 20, 14 X 25, 18 X 18, 20 X 24, 12 X 24, 14 X 30, 16 X 20, 18 X 25, 4 X 24, and 25 X 25.
Q3. Is a furnace filter the same as an air filter?
A3. Both of the systems work the same. The air-handler is the area your air filter resides. So, if your home has a separate heating unit and a cooling unit- yes, a furnace filter is the same as an air filter. And, if your home has central heat and air conditioning – Again Yes. In homes that require moderate heating and cooling, in which a heat pump may be installed for your AC or heating unit, that heat pump uses the same air-handler and the same compressor. So it’s again yes, they both are the same. While the air filter removes dust, bacteria, germ, and allergens, the furnace filter does almost the same job.
Q4. How often should you change your furnace filter?
A4. As a standard, you must change a 1 to 2 inches furnace filter at least every three months. A 4-inches filter needs replacement every six months, and a 5-inches furnace filter needs to be changed every 12 months.
However, these are just rules of thumb. But as we know the fact that every home contracts a unique amount of pollutants, dust, dirt, allergens, and pet dander. So it becomes dependent on some factors when to change filter:
Your home is more dusty than normal.
The filter seems to be dirty and you can’t even see the material of the furnace itself.
You find out some strange smells such as a burning smell near the filter.
Your heating or cooling system is running more frequently than normal.
Apart from this, if you have pets in your home; if you or someone in your home smokes; if you frequently open windows or doors; if you have a heater fan; or if you or anyone in your home is allergic, you are required to replace the filter more frequently. Staying mindful that this appliance is to make your air fresh and healthy, you must change it when the need arises.
Q5. What happens when you don’t change your furnace filter?
A5. A furnace filter is meant to cleanse the air inside your home or your surroundings always. But like every product, they are not designed to work forever. They are regularly in contact with dirt and dust, and they capture them. A furnace filter comes with time validity. As for a one-inch furnace filter, three months are enough to work. After that, they start to fail. So, if you don’t change your furnace filter they will no longer be able to filter the air properly. It will get clogged, and air will not pass through it.
With AC filters, reviews must be performed regularly to check for any contaminants and dust getting into the AC. These particles jam the motor and valves of the AC. Furnace filters are available in cardboard frames and metal frames. The cardboard one with paper filters is disposable, and the metal frame filters can be reused after washing according to the manufacturer’s instructions. You must follow the product’s instructions to increase their longevity.
Q6. Is it OK to run a furnace without a filter?
A6. It becomes critical to use a furnace without a filter. However, if you run a furnace filter for one night, that’s quite okay. But if you are using it for a long time, it traps more particles and they accumulate inside your heating or air conditioning machine.
The main reason you should not run a furnace without a filter is that your furnace can get broken anytime. And the air that is filled with contaminants is dangerous to breathe in. You will be forced to breathe poor quality air. The debris will compile inside the ductwork, by getting trapped in the ribbed aluminum tubes.
Additionally, the clogged air can lead to expensive bills, poor air, overheated furnace, and worn-down HVAC system. Thus, it is not OK to run a furnace without a filter.
Q7. How do I know the size of my furnace filter?
A7. A furnace filter is a must for a clean and pure home environment. There are various sizes available for the same product on Amazon. If you choose the inappropriate size, it might be a waste of money and health. You can choose a perfect size for your furnace filter by following these steps:
Take a measuring tape and get the exact dimension by yourself or you can find the dimensions on your air conditioning machine or heating machine. They are written as l×w×b i.e. 18×20×4. Lay it on the floor and measure from top to bottom for length, left to right for width, and front to back for depth. The result should be three numbers in inches.
When shopping for an air furnace filter, you will find two dimensions as ‘Nominal dimension’ and ‘Actual dimension’. The reason for this difference is that if the filter offered is a bit off by the filter, it will still fit in it. You must go by the actual size.
If the above-mentioned steps don’t work, resort to this last option. You should directly contact your air conditioning manufacturer or can refer to the product manual. They will help you out.
Outside elements such as pollution, seasonal allergens, and dust affect the indoor environment and pollute the air inside your home. It is no less harmful to an individual than outdoor contaminated air. Rather it is 2 to 5 times worse than the outside air. For breathing in a healthy environment, you need to filter your HVAC system with one of the best HVAC filters available out there.
