Replacing an air purifier filter should be simple, but choosing the wrong replacement can leave you with a filter that does not fit or does not provide the filtration your purifier was designed to use. The Vornado MD1-0022 is a genuine True HEPA replacement filter made for a specific group of Vornado air purifiers, with a stated ability to capture 99.97% of airborne particles measuring 0.3 microns or larger. Its main strengths are straightforward compatibility, tool-free replacement, and an annual replacement schedule under normal continuous use. The main limitation is equally important: this is a HEPA particle filter, so you should not treat it as a replacement for the separate carbon filtration used for stronger odor and gas control in compatible multi-stage Vornado systems.
Quick Verdict
Rating: 8/10, Recommended with caveats
Best For: Owners of compatible Vornado air purifiers who want the genuine OEM True HEPA replacement filter.
Bottom Line: The MD1-0022 is a sensible choice when your purifier is on the confirmed compatibility list and you want a genuine Vornado replacement. Its biggest limitation is narrow compatibility, and it does not eliminate the need for a separate carbon filter in Vornado models that use one for odor control.

What Is the Vornado MD1-0022?
The Vornado MD1-0022 is a replacement True HEPA filter for selected Vornado whole-room air purifiers. It is not a complete purifier and it is not a universal filter. You install it inside a compatible Vornado purifier when the existing HEPA filter reaches its replacement interval.
Its job is particle filtration. Vornado states that the filter captures 99.97% of airborne particles measuring 0.3 microns or larger that pass through it. That makes it relevant for particles such as dust, pollen, pet dander, and particle components of smoke. For Vornado purifiers that also use activated carbon filtration, the carbon stage serves a different purpose and should not be confused with the MD1-0022 HEPA filter.
Key Takeaways
- The MD1-0022 is a genuine Vornado True HEPA replacement filter, not a universal air purifier filter.
- It captures 99.97% of airborne particles measuring 0.3 microns or larger that pass through the filter.
- Confirmed compatible models include AC300, AC350, AC500, AC550, PCO200, PCO300, PCO375DC, PCO500, and PCO575DC.
- The filter measures 13 x 11 x 1 inches and weighs 5.6 ounces.
- Vornado recommends replacement about once per year with continuous use, depending on environmental conditions.
- It is disposable, requires no cleaning, and is designed for replacement without tools.

Key Features of the Vornado MD1-0022 Air Purifier Filter
True HEPA Particle Filtration
The main reason to choose the MD1-0022 is its True HEPA filtration. Vornado states that it captures 99.97% of airborne particles measuring 0.3 microns or larger that pass through the filter. In a compatible purifier, that gives you a dedicated particle-filtration stage for common airborne debris such as dust, pollen, pet dander, and smoke particles.
Remember that a filter can only capture particles that actually pass through it. Room size, purifier airflow, fan speed, placement, and maintenance all affect how effectively the complete purifier cleans room air.
Compatibility and Fit
Compatibility is one of this filter’s strongest points and one of its biggest limitations. The MD1-0022 is listed for AC300, AC350, AC500, AC550, PCO200, PCO300, PCO375DC, PCO500, and PCO575DC models.
Using the model number rather than dimensions alone is the safest buying method. A filter that appears physically similar may not seal correctly inside another purifier, and poor fit can allow air to bypass the filter media.
Compact, Lightweight Replacement Design
The filter measures 13 x 11 x 1 inches and weighs about 5.6 ounces. Its light weight makes handling straightforward when you remove an old filter and install a fresh one.
The listing describes the filter as easy to replace with no tools required. That is useful if you want routine maintenance without disassembling the purifier or dealing with a complicated mounting system.
Disposable, Low-Maintenance Operation
The MD1-0022 is a disposable filter rather than a washable one. Vornado’s Amazon listing specifically states that its disposable True HEPA filters require no cleaning.
That simplifies maintenance, but it also means you should plan for recurring replacement. Trying to wash a disposable HEPA filter can damage its media or affect how it fits and performs.
HEPA Filtration vs. Odor Control
This distinction matters when you are comparing replacement filters. The MD1-0022 is primarily a particle filter. Some Vornado purifiers pair HEPA filtration with a separate activated carbon filter that helps adsorb household odors and gases.
That means replacing only the MD1-0022 may not restore every filtration stage in a purifier that also requires a carbon filter. Check the maintenance instructions for your exact Vornado model and replace each filter type at its specified interval.
Pro Tip: Before removing the old filter, note how it sits inside the purifier and confirm the replacement model number on the package. Matching both the purifier model and filter part number is more reliable than judging fit by dimensions alone.
How It Performs in Real Use
For Everyday Dust and Pollen
In a compatible purifier, the MD1-0022 gives you the HEPA stage needed to trap fine airborne particles that pass through the unit. This is the type of use where a genuine replacement makes the most sense: you are restoring the filtration stage the purifier was designed around rather than adapting a filter from another system.
For Homes With Pets
Pet dander is among the particle types associated with HEPA filtration, so the MD1-0022 can help capture airborne pet-related particles that reach the filter. It will not stop fur or dander from being produced, so normal cleaning and proper purifier placement still matter.
For Smoke and Household Odors
HEPA media can capture airborne particles associated with smoke, but smoke also contains gases and odors that particle filtration alone does not fully address. If your Vornado purifier uses a separate activated carbon stage, keeping that carbon filter maintained is important when odor control is one of your priorities.
For Long-Term Maintenance
Vornado recommends replacing the MD1-0022 roughly every year with continuous use, depending on your environment. A home with heavier particle exposure may require closer attention to the purifier’s maintenance indicator or owner guidance, while lighter conditions may be less demanding.
How to Install and Maintain the Vornado MD1-0022 Filter
Filter replacement is designed to be simple and does not require tools. Before opening the purifier, switch it off and unplug it. Open the filter access area according to your purifier’s owner guide, remove the old HEPA filter, and install the MD1-0022 in the same intended position.
Make sure the replacement sits properly in the filter compartment before closing the unit. Correct seating matters because gaps around a filter can allow air to move around the filtration media instead of through it.
Do not wash the MD1-0022. It is a disposable replacement filter. If your purifier has a filter-change indicator or reset procedure, follow the instructions for your specific purifier model after installing the new filter.
Common Mistakes to Avoid
- Ordering by dimensions without checking your purifier model number.
- Washing or soaking the disposable HEPA filter.
- Forgetting that some Vornado models also use a separate carbon filter.
- Installing the filter without checking that it is seated correctly.
- Ignoring your purifier’s maintenance indicator or model-specific owner instructions.
Compatibility and Safety
The most important safety step during replacement is to turn off and unplug your purifier before opening its filter compartment. Follow the owner guide for your exact model because access panels, filter arrangements, and reset steps can vary among compatible Vornado purifiers.
The Amazon listing describes the MD1-0022 as a pleated filter with plastic material components. It is intended as a disposable air-purifier replacement part. Do not modify, cut, wash, or force the filter into a purifier that is not listed as compatible.
Pros and Cons
Pros
- Genuine Vornado replacement part for nine confirmed purifier models.
- True HEPA filtration captures 99.97% of particles 0.3 microns or larger that pass through the filter.
- Tool-free replacement keeps routine maintenance simple.
- Disposable design requires no filter washing or cleaning.
- About one-year replacement guidance reduces how often most users need to change the HEPA stage.
Cons
- Limited to specific Vornado purifier models.
- Disposable design means recurring replacement rather than washing and reuse.
- Does not replace the separate carbon filter used for stronger odor and gas control in compatible multi-stage systems.
Is It Worth the Price?
The MD1-0022 is best viewed as a manufacturer-branded OEM replacement rather than a bargain aftermarket multi-pack. Its value comes from buying the exact Vornado part specified for compatible purifiers, which reduces uncertainty about fit and intended filtration performance.
It makes the most sense if you already own one of the supported Vornado models and want to keep using the manufacturer’s replacement filter system. It is less attractive if your top priority is the lowest possible cost per filter or if you specifically want a washable replacement.
There is also a recurring-cost consideration. The HEPA filter is designed for periodic replacement, and some compatible purifiers use additional carbon or specialty filtration components that have their own maintenance schedules.
How It Compares to Alternatives
The clearest alternative is a third-party filter marketed as compatible with MD1-0022-equipped Vornado purifiers. Those options may emphasize lower cost or multi-packs, but fit, filter construction, and quality can vary. The genuine MD1-0022 makes more sense when OEM compatibility is your priority.
Also remember that the Vornado MD1-0023 activated carbon filter is not a substitute for the MD1-0022. In Vornado models that use both stages, the carbon filter complements the HEPA filter by handling a different part of the filtration process. Other Vornado HEPA cartridges, such as different MD1-series part numbers, should not be assumed compatible unless your purifier documentation specifically lists them.
What Buyers Should Focus On
For this type of replacement part, the most useful buying questions are more practical than cosmetic. Confirm that your exact purifier model is supported, decide whether you prefer the genuine Vornado part over a third-party compatible filter, and remember that this purchase covers the HEPA filtration stage only.
The easy, tool-free replacement design is a meaningful convenience because it keeps routine filter service simple. The more important long-term issue is remembering the replacement schedule and maintaining any separate carbon filtration your particular purifier also uses.
Frequently Asked Questions
Which Vornado air purifiers use the MD1-0022 filter?
The confirmed compatibility list includes AC300, AC350, AC500, AC550, PCO200, PCO300, PCO375DC, PCO500, and PCO575DC. Check the model label on your purifier before ordering because similar-looking Vornado filters are not automatically interchangeable.
How much particle filtration does the MD1-0022 provide?
Vornado states that the True HEPA filter captures 99.97% of airborne particles measuring 0.3 microns or larger that pass through the filter. Actual room-air cleaning also depends on the purifier’s airflow, placement, operating speed, and maintenance.
How often should you replace the Vornado MD1-0022?
Vornado recommends replacement about once per year with continuous use, depending on your environment. Follow the maintenance indicator and owner instructions for your specific purifier if they call for attention sooner.
Can you wash and reuse the MD1-0022?
No. Vornado describes its disposable True HEPA filters as requiring no cleaning. Washing the filter is not part of the recommended maintenance process, so replace it when its service interval is reached.
Does the MD1-0022 remove household odors?
Its primary role is HEPA particle filtration. Compatible Vornado purifiers that use activated carbon rely on that separate carbon stage for stronger adsorption of odors and gases, so you should maintain both stages when your purifier requires them.
Do you need tools to replace the filter?
The MD1-0022 is listed as easy to replace with no tools required. You should still switch off and unplug your purifier first and follow the filter-access instructions for your exact Vornado model.
Can you use the MD1-0022 in a non-Vornado air purifier?
It is designed for specific Vornado air purifier models. Do not assume that another purifier is compatible because its filter compartment appears similar or because the dimensions seem close.
Do you also need a carbon filter?
That depends on your Vornado purifier model. Several compatible Vornado systems use a separate activated carbon stage in addition to the MD1-0022 HEPA filter, so check your purifier’s owner guide and maintain each required filter separately.
The Bottom Line
The Vornado MD1-0022 is a strong fit for owners of confirmed compatible Vornado purifiers who want the genuine True HEPA replacement filter, simple tool-free servicing, and a roughly annual replacement schedule. Skip it if your purifier is not listed as compatible, if you require a washable filter, or if you expect one HEPA filter to replace the separate carbon stage used for odor control in some Vornado systems.
