Give Your Car’s Cabin Air a Deep Clean with the Right HEPA Filter
Your car’s cabin air can get filled with all kinds of allergens, pollutants, and odors that make every drive unpleasant. From pollen and pet dander to exhaust fumes and food smells, the air inside your car takes a real beating. But you can fight back against contaminants with the help of a high-quality HEPA cabin air filter like those made by Microgard.
Microgard’s HEPA cabin air filters use advanced filtration technology to trap tiny particles and purify the air inside your vehicle’s cabin. This allows you to breathe cleaner, fresher air while driving. But with so many different types of cabin air filters on the market, how do you know which one is right for your car?
This comprehensive buying guide covers everything you need to know about choosing the perfect Microgard HEPA cabin air filter for your vehicle. We’ll explain how HEPA filters work, where to buy them, how often they need replacing, plus provide tips on installation, maintenance and more. Let’s get started!
What is a Microgard HEPA Cabin Air Filter?
Microgard is a leading manufacturer of high-efficiency cabin air filters for a wide variety of makes and models. Their HEPA-qualified filters are designed to capture 99.97% of fine particulates down to 0.3 microns in size. This includes dust, pollen, mold spores, bacteria, and more.
HEPA stands for “high efficiency particulate air” filtration. To qualify as true HEPA under government standards, an air filter must remove a minimum of 99.97% of particles measuring 0.3 microns from the air that passes through. This tiny particle size was chosen because it represents the most difficult size for filters to capture.
By removing nearly 100% of particles this small, a HEPA filter ensures it will also trap larger pollutants, allergens, and microbes too. This level of impeccable filtration makes HEPA cabin air filters far superior to standard paper or granulated carbon filters.
Microgard’s HEPA cabin air filters utilize a pleated filter medium for maximum surface area inside a tightly sealed frame. This allows high airflow rates while capturing the tiniest airborne particles that pass through the HVAC system. The result is noticeably cleaner, fresher air throughout your vehicle’s cabin.
How Does a Microgard HEPA Cabin Air Filter Work?
Microgard HEPA cabin air filters utilize a multi-layer filtration media enclosed in a durable plastic frame. The filters are designed to simply drop into your existing cabin air filter housing, typically located behind the glove box.
As air passes through your vehicle’s HVAC system, it first goes through a pre-filter layer that traps larger particles like dust and pet hair. The air then moves through the tightly packed HEPA filter medium where miniscule particulates are captured at an efficiency exceeding 99.97% by the dense fiber matrix.
The filters have an angled media pack design allowing maximum airflow and surface area within the confined space. The sealed edges prevent bypass so that all cabin air moves through the filter properly. The end result is air purification down to 0.3 microns for superior removal of fine particulates.
Several layers work together for comprehensive filtration:
- Pre-filter layer – Catches larger particles like dust and pet dander
- HEPA media – Removes 99.97% of particles down to 0.3 microns
- Protective backing – Prevents tears and maintains the HEPA media’s integrity
This combination maximizes particle capture while allowing proper airflow to pass through the vehicle’s ventilation system. Microgard HEPA cabin air filters deliver purification you can breathe easy about!

How Often Should I Replace a Microgard HEPA Cabin Air Filter?
Microgard recommends replacing your HEPA cabin air filter every 12,000 to 15,000 miles. However, if you drive often in dusty conditions or polluted environments, changing it more frequently is a smart idea. The same applies if you live with pets that might shed dander into your car’s interior.
Here are signs indicating it’s time to swap in a new filter:
- Reduced airflow from vents
- Increased dust or odors in cabin air
- Existing filter is clogged with dirt and debris
Replacing a dirty, spent air filter with a fresh Microgard HEPA filter will restore purified airflow and protect your car’s HVAC system. Don’t wait until your filter appears obviously filthy, as particulate buildup happens gradually. Stick to yearly filter changes for optimal performance.
Checking your cabin air filter should be part of your routine maintenance schedule. Set a reminder to swap it out every 10K to 15K miles. Keeping it changed at proper intervals will ensure the highest air quality inside your vehicle’s cabin for both driver and passengers.

How Do I Maintain a Microgard HEPA Cabin Air Filter?
Microgard HEPA cabin air filters are designed to be maintenance-free provided you follow the proper replacement interval of 12,000-15,000 miles. However, here are a few tips for optimal filter performance:
- Check your filter briefly at oil change intervals to note any debris buildup.
- Use your car’s AC and fan settings regularly to keep air cycling through the filter.
- Keep the filter housing cover properly closed to avoid water and dirt entry.
- Vacuum interior carpets often to prevent cab air contamination.
- Avoid spraying perfumes, cleaners or other chemicals near the filter.
- Have your car’s cabin air intake ducts cleaned if they contain excessive accumulated debris.
- Change your filter proactively before long road trips or allergy season begins.
Simple periodic inspection plus following good car interior hygiene practices will keep your Microgard filter working at max effectiveness. But don’t attempt to wash or clean filters, just replace them.
What is the Lifespan of a Microgard HEPA Cabin Air Filter?
You can expect a new Microgard HEPA cabin air filter to last approximately:
- 12,000 to 15,000 miles
- 1 to 2 years
But keep in mind driving conditions impact lifespan considerably. Frequent stop-and-go traffic, dusty roads, and polluted cities put more strain on your filter. The same applies to having pets shedding inside your car.
Check your filter at least yearly when you change oil and other fluids. Note if any debris buildup is present. Check your vehicle mileage as well. Installing a fresh Microgard HEPA filter every 10K to 15K miles ensures you get full value from each one.
Adhering to this replacement interval also safeguards your car’s HVAC system from the effects of restricted airflow. Never drive until your filter appears obviously filthy before changing it out.
With proper annual filter changes, you’ll enjoy optimized performance and clean cabin air. Consider signing up for a filter subscription service that delivers new ones on schedule. Or at least set your own calendar reminders.
Stay diligent about installation of new Microgard HEPA filters approximately one to two times yearly. Your vehicle’s air quality and engine performance depend on it!
