Air conditioning filters play a big part in keeping the air we breathe clean. They come in many kinds, like fibreglass, pleated, HEPA, UV, electrostatic, and activated carbon filters.
Each kind is special – they can trap dust, stop bad smells or even kill germs! Filters have something called a MERV scale rating; higher numbers mean they catch more dirt. While fibreglass filters are cheap to buy, people with allergies should go for better ones like pleated filters that score between MERV 5-8.
HEPA filters are top-notch at catching lots of tiny particles that could make us sick.
Some homes might need UV filters to zap harmful bugs out of the air but aren’t great at grabbing dust. Electrostatic types use a clever trick with electricity to pull in small bits floating around.
And if you’ve got stinky odours or chemicals in the air from paint or cigarettes, activated carbon tackles these well.
But remember: no matter which filter you pick for your air conditioner (AC), changing it regularly keeps your air fresh! How often depends on things like how big your home is and whether you’ve got pets who shed fur everywhere.
Next up: let’s discover what makes each type of filter unique and how to choose the best one for your AC!
Understanding the Function of Air Conditioning Filters
Air conditioning filters play a vital role in maintaining indoor air quality. They trap dust, pollen, pet dander, and other small particles that may harm your health. Good filters keep the HVAC system clean and running efficiently.
Clean air flows through the ducts and into your home without carrying unwanted pollutants.
The MERV rating helps you understand how well a filter can catch smaller particles. Filters with higher ratings stop more contaminants from passing through them. This keeps the air fresher and cleaner for everyone to breathe.
It’s essential for people with allergies or asthma because good filtration reduces irritants in the air that can trigger symptoms.
Types of Air Conditioning Filters
Fiberglass Air Filters, Pleated Air Filters, HEPA Filters, UV Filters, Electrostatic Filters, and Activated Carbon Filters are all types of air conditioning filters that serve different purposes in improving indoor air quality.
Each type has its own unique features and benefits for effectively filtering out airborne particles and contaminants to ensure cleaner air within your home or commercial space.
Fiberglass Air Filters
Fiberglass air filters are common in many homes because they’re cheap and don’t make your HVAC system work too hard. These filters catch big pieces of dust, but tinier bits like pollen or pet hair might slip through.
If you suffer from allergies or breathing issues, these may not be the best choice since they won’t trap all the allergens in the air.
Moving on to pleated air filters, we find a better option for trapping smaller particles without blocking airflow.
Pleated Air Filters
Pleated air filters provide a step up in air purification. They catch more dirt and dust than regular fiberglass filters. With their unique design, they trap small particles other filters might miss.
This makes them great for homes with pets or people with allergies.
These filters boast MERV ratings from 5 to 8, showing they are efficient at cleaning the air you breathe. Those living with respiratory issues often choose pleated types for better indoor air quality.
They’re also easy to install in most HVAC systems, helping to keep your home’s climate control running smoothly without blocking airflow too much.
HEPA Filters
Moving on from pleated filters, HEPA filters offer some of the best protection against tiny particles. These high-efficiency particulate air filters can trap 99.97% of dust, pollen, mould, bacteria, and any airborne particles with a size of 0.3 microns (µm).
They play a crucial role in maintaining indoor air quality for homes and businesses alike.
HEPA filtration systems are ideal for those who suffer from allergies or respiratory issues as they excel at removing irritants from the air. These powerful air cleaners create cleaner breathing spaces by reducing pollutants that can lead to health problems.
In settings that require extremely clean air like hospitals and clean rooms, HEPA filters are essential. They ensure that even the smallest contaminants are captured, leaving behind only fresh and pure air for ventilation systems to circulate.
UV Filters
UV filters in air conditioning systems do more than just cool the air; they work to make it healthier too. They use ultraviolet light to kill germs like viruses and bacteria. This feature is great for improving indoor air quality, especially in places where hygiene is a top priority.
While UV filters are good at getting rid of microorganisms, they’re not the best choice for removing dust or other particles from the air. So if you want cleaner air that’s also free of tiny unwanted guests, consider pairing UV with another type of filter that catches those bits.
Now let’s check out how electrostatic filters can help keep your space clean and comfortable.
Electrostatic Filters
Moving from UV Filters that use light to clean the air, Electrostatic Filters employ a different tactic. They harness static electricity to capture dust and other small particles. As air moves through them, it makes contact with fibres that carry an electric charge.
This effect creates a magnetic field around the fibres. Small particles like pollen, pet dander, and smoke get attracted to this field and stick to the filter.
These filters not only trap common allergens but also snare bacteria and viruses. Because of their efficiency, they are great for people with allergies or breathing issues. You can wash and reuse Electrostatic Filters many times over.
They save you money in the long run by cutting down on replacement costs compared to single-use filters with lower MERV ratings. These eco-friendly options mesh well with efforts to maintain cleaner indoor air quality while reducing waste from disposable products.
Activated Carbon Filters
Activated carbon filters work wonders for keeping indoor air fresh. They use a special form of carbon that traps odours, gases, and chemicals like VOCs. These filters are perfect for homes with furry friends or anyone who smokes inside.
They also help people with breathing issues by clearing out unwanted smells and harmful compounds.
These filters pack a powerful punch against stinky air problems. While they don’t catch dust or allergens like some other types, their knack for nabbing odours makes them an essential part of many HVAC systems.
People who care about the smell and chemical cleanliness of their air should definitely consider activated carbon filters in their home or office setups.
Selecting the Right Air Conditioning Filter
When selecting an air conditioning filter, consider the following factors:
- Minimum Efficiency Reporting Value (MERV) rating to determine the filtration efficiency.
- Size of the filter, ensuring it fits perfectly into the HVAC unit without gaps for air leakage.
- Type of contaminants in your environment, targeting filters that effectively capture specific particles such as pet dander or mould spores.
- Frequency of filter replacement based on manufacturer’s recommendations and usage conditions.

How Often Should You Swap Out Your Aircon Filter?
It is imperative to swap out your aircon filter regularly to ensure efficient functioning. Here’s how often you should do it:
- Fiberglass Air Filters: These need replacement every 30 days as they are designed for basic protection and are not reusable.
- Pleated Air Filters: These have a longer lifespan, typically requiring replacement every 3 months, but check monthly if used frequently.
- HEPA Filters: Due to their high filtration efficiency, these filters generally need replacement every 6-12 months.
- UV Filters: Replace UV bulbs annually for optimal performance in eliminating microorganisms from the air.
- Activated Carbon Filters: The activated carbon should be replaced every 3-6 months to maintain effective odor removal.
