Mini splits can be a great addition to your home's cooling and heating system, but did you know they often come equipped with air filters to improve indoor air quality? Some mini splits have washable filters that can be cleaned regularly, while others have disposable filters that need to be replaced.
Many mini splits have a built-in air filter that captures dust, pollen, and other airborne particles, making the air in your home cleaner and healthier to breathe. This is especially important for people with allergies or respiratory issues.
Some mini splits have a high-efficiency air filter that can capture particles as small as 0.3 microns, which is smaller than the diameter of a human hair. This means you can breathe easier knowing the air in your home is clean and fresh.
Regular filter maintenance is key to ensuring your mini split continues to perform well and provide clean air.
Do Mini Splits Have Air Filters?
Mini splits do have air filters, thanks to filters installed within the units. Some brands, like Mitsubishi Electric, are known for their great air filtration systems.
These filters can help control your air quality and give you fresh, filtered air. Ductless mini-splits are perfect for homes without ductwork.
You can expect to find different types of filters, including HEPA filters. HEPA filters use electricity to reduce particles blown through the unit and into your home.
Mini-split filter options are endless, so it's essential to research before shopping. You'll want to know what MERV means, which indicates how fine a product's filtration will be.
The MPR, or microparticle performance rating, will also tell you how good the unit is at catching particles smaller than a single micron. Understanding these key terms will help you pick the best type of mini-split air purifier and filters for your home and family.
Mini split units may use HEPA filters to remove mold, pathogens, dust mites, pet dander, and other allergens from your air.

Filter Maintenance Importance
Proper maintenance helps to ensure that your filters keep your air as clean as possible. Most heat pumps last 10 years, and you can easily clean them yourself. Others may need to be replaced annually rather than cleaned.
Filters need to be clean to work, and the more frequently you replace them, the better your mini-split will perform. A dirty or overused filter will not purify the air in your home and decrease the efficiency of your mini-split.
You should replace mini-split air purification filters once you've gotten your use out of them. Some manufacturers suggest replacing filters every 3 months, while some suggest every 6 months. The more frequently you replace them, the better your mini-split will perform.
Cleaning your filters on your mini-split every four weeks will keep them in optimal condition. To clean a filter, simply remove it from the mini-split unit and wipe it down with a dry cloth or soap and clean water.

Ductless Splits
A ductless mini split circulates, cools, and conditions the air that is already in your home, it does not bring in air from the outside.
The filtration system of a mini split, when properly maintained, actually puts out air that is much cleaner than "fresh" air from outdoors.
You'll want to inspect and clean your system as recommended in accordance with the manufacturer's instructions to prevent dirt and debris from accumulating in its coils and filters.
Ductless Splits Introduce Fresh Air
Mini-splits have air purifiers, thanks to filters that are installed within the units, allowing you to control your air quality and get fresh, filtered air.
Some mini-split systems, like Mitsubishi Electric indoor air handlers, are known for having great air filtration systems, perfect for homes without ductwork.
A ductless mini split circulates, cools, and conditions the air that is already in your home, running quietly and efficiently.
When properly maintained, a mini split's filtration system puts out air that is much cleaner than "fresh" air from outdoors.
High Efficiency Particulate Air filters, or HEPA filters, use electricity to reduce particles blown through the unit and into your home, making them a great option to consider.
Ductless Splits Get Moldy?
A mini split system can accumulate dirt and debris in its coils and filters over time.
This can lead to decreased efficiency and even toxic mold that can cause serious health complications.
Mold growth can be especially problematic while the system is in air conditioning mode.
Regular inspection and cleaning of your system, as recommended by the manufacturer, is crucial to prevent mold buildup.

Multi-Stage Filtration
Mini-split air filters are designed to work efficiently, and one of the key features is multi-stage filtration. This means that the air moves through two different filters, each designed to capture a specific type of pollutant.
The first filter removes odors and fine particulates, making a big difference in indoor air quality. It's like a breath of fresh air, especially for people with sensitivities.
The second filter takes out even more allergens, pollutants, and particulates, providing an extra layer of protection. This is especially important for people with respiratory issues or allergies.
Some mini-split systems also have UV lamps in their units to kill bacteria that cycle through them. This adds an extra layer of protection to the multi-stage filtration process.
In high-end mini-split models, you can find filters with nanometer-scale mesh platinum catalysts that capture tiny little nanoparticles. These filters are designed to absorb cooking odors, smoke, and other smells in your home.
Here are some examples of advanced filters you might find in high-end mini-split systems:
- Hybrid filters: These filters are infused with catechin, a bioflavinoid found in green tea, and charged with static electricity. They absorb odors and capture dust, bacteria, and viruses.
- Platinum deodorizing filters: These filters use a platinum catalyst to absorb cooking odors, smoke, and other smells in your home.
- Anti-allergy enzyme filter: This filter captures bacteria, viruses, dust, pollen, and germs, and then breaks down the proteins in the allergens.
Hepa Filters
Mini split units may use HEPA filters to remove mold, pathogens, dust mites, pet dander, and other allergens from your air.
HEPA filters are designed to capture dust and catch and deactivate microscopic bacteria and viruses. They can also absorb odors like tobacco smoke.
Some mini splits come with other types of filters, such as carbon, nano, enzyme, or antimicrobial filters. It's a good idea to consult manufacturer's specifications or ask a tech to determine which types of filters are compatible with your unit and how often they need to be cleaned or changed.

You can also choose between different filter options, depending on the model you buy. The highest-end mini splits tend to offer multi-filtration with various types of filters.
Here are some examples of high-end filters:
- Hybrid filters: These filters are infused with catechin and charged with static electricity, capturing dust and deactivating microscopic bacteria and viruses.
- Platinum deodorizing filters: These pre-filters use a platinum catalyst to absorb cooking odors, smoke, and other smells in your home.
- Anti-allergy enzyme filter: This pre-filter captures bacteria, viruses, dust, pollen, and germs, and then breaks down the proteins in the allergens.
Some people may want to consider adding a whole home filtration system to their heat pump for extra protection.
Slide Out Filters
To access and clean your mini-split air filters, you'll need to slide them out. Some manufacturers suggest replacing filters every 3 months, while others recommend every 6 months.
The filters are held in place with grooved channels on each side. You'll want to gently push from the bottom up and out to release the filter from the track.
You can easily remove the filters yourself from the front of the indoor air handling unit. Take care not to shake dust from the filter all over that you'll have to clean later.
The more frequently you replace your mini-split air purification filters, the better your mini-split will perform. A dirty or overused filter will not purify the air in your home and decrease the efficiency of your mini-split.
