How It Works – Filtration Stages Explained

Our air purifier filters use a multi-stage filtration system to clean your indoor air effectively. Here’s a quick look at each stage:

  • Stage 1: Pre-filter

    This washable layer catches large particles like dust, pet hair, and lint. It protects the main filters and extends their lifespan by handling the bigger stuff first.

  • Stage 2: True HEPA Filter

    The heart of the system, our True HEPA filters (H13/H14 grade) trap 99.97% of tiny particles down to 0.3 microns—including pollen, mold spores, and smoke. It’s essential for allergy relief and clean breathing.

  • Stage 3: Activated Carbon Filter

    This stage removes odors, volatile organic compounds (VOCs), and harmful gases. It’s great for smoke removal and keeping indoor air fresh.

  • Optional Stage 4: Ionizer/UV Light

    Some filters add an ionizer or UV sterilizer to kill bacteria and viruses, improving overall air hygiene. This depends on your air purifier model.

Together, these stages create a powerful defense against indoor pollutants, capturing dust, allergens, pet dander, smoke, and more.

How to Choose the Right Air Purifier Filter for Your Model

Choosing the right air purifier replacement filters is simple if you follow a clear checklist. Here’s how I recommend you do it.

Find the Right Size and Part Number

Start with the basics: size and part code.

  • Check the label on your existing filter for:
    • Model name (e.g., Core 300, AM11, Blue Pure 211+)
    • Filter code (e.g., Core 300-RF, F2, 360º HEPA)
  • Look in:
    • The user manual
    • The sticker on the purifier body
    • Your online order history for previous HEPA filter replacement purchases
  • If the size is listed in inches, match it carefully (length × width × depth). Even a 0.5″ mismatch can cause air bypass.
  • When in doubt, measure your old air cleaner filter and compare it with our spec sheet, or use our complete guide on what size air filter you need.

Check Brand and Model Compatibility

Always match brand + model + filter type.

  • Common brands we support:
    • Xiaomi, Dyson, Levoit, Winix, Blueair
    • Honeywell, Medify, Coway, and more
  • Match these three details:
    • Brand: e.g., Levoit
    • Purifier model: e.g., Core 300, Core 400S, Dyson TP04, Winix 5500-2
    • Filter style: True HEPA filter, H13 HEPA filter, pre-filter + HEPA + carbon combo, etc.
  • Look for wording like:
    • “Air purifier filter compatible with Levoit Core 300”
    • “Replacement air filter for purifier model Winix 5500-2”
  • If your exact model is not listed, send us:
    • Brand + full model number
    • A photo of your current filter
    • Basic dimensions
      We can usually match a compatible air purifier filter or suggest a custom size air purifier filter.

OEM vs Compatible Air Purifier Filters

Both OEM air purifier filters and high‑quality compatible filters can work well. It depends on your priorities.

Situation / PriorityBest Choice
New purifier under strict warrantyOEM air purifier filter is the safe option
Allergies, asthma, medical needsOEM or certified H13 HEPA filter
Lower yearly cost with strong performanceQuality compatible filter (like Komtfil)
Need bulk, 2-pack, 4-pack, 6-pack optionsCompatible replacement filters
Older purifier, OEM filters hard to findCompatible or custom air purifier filters

We manufacture OEM-grade compatible filters. Our Komtfil filters use true HEPA media, thick activated carbon filter layers, and tight tolerances, so you can often match or beat OEM performance at a lower cost.

What to Look for in Long-Life Air Purifier Filters

If you want fewer changes and better value over the year, focus on long-life air purifier filter features:

  • True HEPA or H13 media: Look for 99.97% at 0.3 microns or better; this matters for PM2.5, pet dander, and pollen.
  • More pleats, deeper media: More surface area = higher dust‑holding capacity and longer life.
  • Thick activated carbon filter: Heavier carbon weight and solid iodine value rating for better smoke and odor control.
  • Pre-filter included: A washable pre-filter catches hair and large dust, extending HEPA and carbon life.
  • Clear rated service life: Example: “6–12 months at normal home use.” We design Komtfil long-life filters around realistic U.S. usage patterns (pets, AC, heating, wildfire smoke).
  • Stable frame and seal: A rigid frame and good gasket prevent air bypass and keep CADR high over time.

When you combine the right size, correct brand/model match, and a long-life filter design, you get better air, fewer replacements, and a lower total cost per year.

Air Purifier Filter Compatibility Guide

Picking the right air purifier replacement filters starts with compatibility. If the filter doesn’t match your exact model, you lose airflow, CADR, and filtration performance, even if it “almost” fits.

Brand-by-brand air purifier filter compatibility

We organize our air purifier filters by brand, series, and model in a PDF so you can match them quickly:

  • Major brands we support: Xiaomi, Dyson, Levoit, Winix, Blueair, and many others
  • Each filter listing shows: brand + series + model + original part number + our compatible code
  • Look for phrases like “air purifier filter compatible with Dyson TP04/TP06/DP04” or “replacement air filter for purifier Levoit Core 300/300S”
  • For our own units and OEM air purifier filters, we follow the same format so you can standardize across your fleet or facilities

Model numbers and popular filter codes

To find the right HEPA filter replacement, always match at least one of these:

  • Full purifier model (for example: Levoit Core 300Blueair 211+Winix 5500-2)
  • Original filter code (for example: Core 300-RFH13 HEPA filter4-in-1 air purifier filter set)
  • Label on your old cartridge (often a sticker showing “pre-filter + HEPA + carbon combo” or “smoke removal carbon filter”)

If you’re unsure which efficiency level you need, our detailed MERV ratings guide for air filters helps you understand filtration performance before you order.

Using an Online search to match your device

Some online searches and tools are built to make matching simple:

  • Type in your brand + model (for example: “Dyson HP04 filter”)
  • Add any original part number or filter code from your manual or old filter
  • Narrow down by H13 HEPA filteractivated carbon filter, or long-life air purifier filter, depending on your needs (pets, smoke, allergies, offices)

Once you see a result labeled as an air purifier filter compatible with your exact model, you’re good to go.

If you can’t find your exact air cleaner filter listed

If your model isn’t in the list, don’t guess; use these steps instead:

  • Check the user manual or label on the old filter for model and part numbers
  • Measure the length, width, and depth in inches to see if a custom size air purifier filter is needed
  • Send us your inquire

FAQ's

Most Popular Question

In normal conditions, you can replace your air purifier filter every 10-12 months.

The HEPA filter will be clogged and lose its filter efficiency if you don't replace it. What's more, it will cause 2nd pollution in your room.

I don't recommend doing this. Although it will save money, the potential environmental pollution risks it will bring are difficult to estimate.

HEPA filters cannot remove odors, you can use our activated carbon filters to remove smells and odors.
