Finding the right replacement filter can be harder than it looks because several compact air purifiers use a similar round filter shape. The Improvedhand MK01 & MK06 Filter Replacement is a four-pack designed for several compatible purifier models, with a 4-in-1 filtration structure that includes an H13 True HEPA layer and activated carbon. Its biggest advantage is broad model compatibility and multiple filters in one package, but you still need to confirm the exact purifier model before ordering. This review explains the fit, filtration design, installation, replacement schedule, limitations, and who gets the most value from it.
Quick Verdict

What Is the Improvedhand MK01 & MK06 Filter Replacement?
The Improvedhand MK01 & MK06 Filter Replacement is a third-party replacement filter pack for a group of compact air purifiers that share this filter format. The package contains four filters, making it suitable for buyers who prefer to keep several replacements on hand instead of purchasing one filter at a time.
Each filter uses a 4-in-1 filtration structure. The listed stages include a pre-filter, an upgraded blue filter layer, an H13 True HEPA filter, and an activated carbon layer. These stages have different jobs, from catching larger debris such as hair and household dust to helping reduce smaller airborne particles and common household odors.
The product is not a universal air purifier filter. It is intended only for the purifier models listed as compatible, so model verification is the first step before you consider filtration performance or pack value.
Who Should Buy It?
Best For
- Owners of a purifier specifically listed as compatible with this MK01/MK06 replacement filter.
- Homes that want a multi-stage filter with both particle filtration and activated carbon.
- Buyers who prefer a four-pack so replacement filters are available for future maintenance.
Skip If
- Your purifier model does not appear on the compatibility list.
- You specifically want an official OEM replacement made by your purifier’s original manufacturer.
- You only need one replacement filter and do not want to store a four-pack.
Before You Buy: Do not assume a filter will fit because its shape looks similar to your current filter. Check the exact model number printed on your air purifier and compare it with the compatibility list before ordering.
How the 4-in-1 Filtration System Works
Pre-Filter for Larger Debris
The first filtration stage is the pre-filter. Its role is to catch larger material such as visible dust, lint, fibers, hair, and pet fur before that debris reaches the finer filter layers.
This matters because a purifier used around pets, fabric, carpet, or frequently opened windows can collect larger particles quickly. Keeping those particles on the outer stage helps the finer filter media focus on smaller airborne material.
Upgraded Blue Filter Layer
The Improvedhand listing also identifies an upgraded blue filter layer within the filter assembly. It sits between the coarser filtration and the remaining fine-particle and carbon stages as part of the product’s four-stage design.
You do not need to perform separate maintenance on this layer. The filter is sold as one complete replacement unit, so all filtration stages are replaced together when the filter reaches the end of its useful service interval.
H13 True HEPA Filtration
The main particle-filtration stage is listed as an H13 True HEPA filter. This is the stage intended to capture much finer airborne material than the outer pre-filter can handle.
For everyday use, that makes the filter more relevant in rooms where airborne dust, pet dander, pollen, and smoke particles are concerns. Actual room-air results still depend on the purifier itself, fan speed, room conditions, placement, and how regularly you operate the unit.
Activated Carbon for Odors
The final listed filtration component is activated carbon. Carbon is used to adsorb odor-causing compounds rather than simply trapping visible dust.
This layer can be useful in homes dealing with cooking smells, pet odors, or occasional smoke. It should not be treated as a substitute for ventilation or removal of a serious pollution source, but it adds odor-focused filtration that a particle-only filter would not provide.
Compatibility and Fit
The strongest reason to check this product carefully is its broad but specific compatibility list. The Improvedhand MK01/MK06 replacement is listed for the following air purifiers:
- AROEVE: MK01 and MK06
- ToLife: TZ-K1
- Kloudi: DH-JH01
- POMORON: MJ001H
- Intelabe: EPI080 and EP1080
- Elechomes: EPI081 and EP1081
That cross-brand compatibility can make the four-pack useful if you own one of these specific models. It also creates an easy buying mistake, because similar compact purifiers can use filters with slightly different dimensions or internal shapes.
Before ordering, read the label on your purifier rather than relying on an old receipt or a photo online. Model names that differ by only a few letters can sometimes use different replacement parts.
Pro Tip: Take a photo of the model label on the bottom or back of your purifier before shopping. Comparing that label with the compatibility list is faster and safer than trying to identify the filter by appearance.
How to Install the Replacement Filter
Installation is designed to be straightforward and does not require special tools. The exact cover mechanism can vary by purifier, so your purifier manual should take priority if its instructions differ.
| Step | What to Do | Mistake to Avoid |
|---|---|---|
| 1 | Turn the purifier off and unplug it. | Working on the purifier while it is powered. |
| 2 | Open the filter compartment according to your purifier manual. | Forcing a cover or locking tab. |
| 3 | Remove the used filter carefully. | Shaking accumulated dust back into the room. |
| 4 | Remove all protective packaging from the new filter. | Installing a filter while it is still wrapped. |
| 5 | Seat the filter fully and follow any direction markings. | Leaving the filter tilted or poorly seated. |
| 6 | Close the compartment, restore power, and reset the filter indicator if your purifier requires it. | Assuming every model uses the same reset procedure. |
A correct fit should allow the filter compartment to close normally without excessive force. If the cover will not lock after installation, stop and recheck the filter orientation and purifier model before operating the unit.
How It Performs in Real Use
For Everyday Household Dust
During normal daily use, the pre-filter and H13 True HEPA stage handle different parts of the particle load. The pre-filter catches larger debris first, while the finer filtration stage handles smaller airborne particles passing through the purifier.
This arrangement is most useful when you operate the purifier consistently rather than only switching it on after dust becomes noticeable. Air purifier performance also depends on the purifier’s airflow and room conditions, not the replacement filter alone.
For Homes With Pets
Pet households can place extra demand on a filter because hair, dander, dust, and odors may all be present at the same time. The pre-filter helps with larger hair and debris, while the particle and carbon stages address different airborne contaminants and odors.
Check the filter more often in a home with heavy shedding. The listed 6 to 8 month schedule is a general recommendation, not a guarantee that every household will get the same service life.
For Kitchens and Odor-Prone Rooms
The activated carbon layer adds a useful odor-control component for cooking smells and other common household odors. A purifier works best as part of normal source control, so strong cooking smoke or persistent odors should still be handled with suitable ventilation when possible.
For Long-Term Maintenance
The four-pack is particularly convenient for long-term ownership. You can replace the filter and still have additional units available instead of shopping for another replacement each time the purifier needs maintenance.
Storage still matters. Keep unused filters in their protective packaging and in a clean, dry location until you are ready to install them.
Why Regular Filter Replacement Matters
The product listing recommends replacing the MK01/MK06 filter approximately every 6 to 8 months, depending on use and environmental conditions. That interval works as a planning guideline rather than a fixed deadline.
A filter gradually accumulates the particles pulled through the purifier. As loading increases, airflow and filtration performance can be affected. Homes with pets, smoke exposure, high dust levels, frequent purifier operation, or nearby construction may need more frequent checks.
Instead of relying only on the calendar, look at how the purifier is behaving. Reduced airflow, a visibly dirty filter, persistent odors, or a filter-change indicator can all justify checking the filter sooner.
Maintenance and Storage Tips
- Check the filter periodically instead of waiting until the maximum suggested replacement interval.
- Keep unused replacement filters sealed until needed.
- Store spare filters somewhere clean and dry.
- Do not wash the complete replacement filter unless the product instructions specifically state that a particular component is washable.
- Follow your purifier’s manual when cleaning the housing, intake, and surrounding surfaces.
- Reset the filter reminder only after completing the maintenance required by your particular purifier.
The filter is a replaceable consumable rather than a permanent washable cartridge. Washing a filter that was not designed for water can damage its media and reduce its ability to function as intended.
What to Do When the Filter Does Not Fit
If the new filter will not seat correctly, do not force the purifier cover closed. Most fit problems can be narrowed down by checking the purifier model, filter orientation, packaging, and condition of the replacement filter.
| Issue | What to Check |
|---|---|
| Wrong purifier model | Compare the exact model label with the published compatibility list. |
| Incorrect orientation | Follow the direction and placement instructions for your purifier. |
| Protective packaging remains | Remove all shipping or protective wrapping before installation. |
| Filter is damaged | Inspect the frame and filter media for shipping damage or deformation. |
| Cover still will not close | Remove the filter and recheck compatibility rather than forcing the cover. |
Pros and Cons
Pros
- Four replacement filters are included in one package.
- 4-in-1 filtration combines coarse, fine-particle, and activated-carbon stages.
- H13 True HEPA filtration is included in the listed design.
- Compatible with several specific purifier models across multiple brands.
- Replacement is designed to be completed without special tools.
Cons
- Compatibility is limited, so a similar-looking purifier may still use a different filter.
- It is a third-party replacement rather than the official OEM filter for every listed purifier.
- The 6 to 8 month replacement interval can vary with dust, pets, smoke, and operating time.
Is It Worth the Price?
The Improvedhand MK01/MK06 replacement is best viewed as a value-focused multi-pack. You receive four filters rather than a single replacement, which can make sense if you plan to keep the same purifier for several replacement cycles.
The strongest value comes from convenience. Once you confirm compatibility, having spare filters available removes the need to search for the correct model every few months. The 4-in-1 construction also combines particle and odor-focused filtration in one replacement unit.
It is less attractive if you only need one filter, expect to replace your purifier soon, or prefer to use the original manufacturer’s filter. In those situations, buying four at once may leave you with filters you never use.
How It Compares to Alternatives
If you use an AROEVE MK01 or MK06 and prefer an OEM part, AROEVE sells its own official MK01/MK06 replacement filters. The official option may appeal to buyers who prioritize manufacturer-direct compatibility, while the Improvedhand option focuses more on cross-brand compatibility and a four-filter package.
Nispira also sells an MK01/MK06 and TZ-K1-compatible replacement in a smaller two-pack with HEPA, activated carbon, and pre-filter stages. Cleangela offers another compatible 4-in-1 option. The Improvedhand four-pack makes the most sense when your exact model is supported and you want several replacement filters in one purchase.

The Improvedhand listing describes a pre-filter, upgraded blue filter layer, H13 True HEPA filter, and activated carbon filter. Together they address larger debris, finer airborne particles, and common household odors.
What should I do if the replacement filter does not fit?
Do not force it into the purifier. Check the exact purifier model, remove any protective packaging, verify the installation direction, and inspect the replacement filter for shipping damage or deformation.
Who should skip this filter?
Skip it if your purifier is not specifically listed as compatible or if you require an OEM replacement from the purifier manufacturer. It may also be unnecessary if you need only one filter and do not want to store the remaining three.
The Bottom Line
The Improvedhand MK01 & MK06 Filter Replacement is a strong option for owners of the listed compatible air purifiers who want a four-pack with pre-filtration, H13 True HEPA filtration, and activated carbon. Its biggest advantage is the combination of broad compatibility and multiple replacement filters, while its main limitation is that fit must be confirmed by exact purifier model. If your purifier is on the compatibility list and you expect to keep using it through several filter changes, this 8.3/10 option is worth considering.
