Replacement filters can be confusing because the part number may match while the filter design, package contents, and filtration claims differ. The PUREBURG 990051000 Replacement True HEPA Filter Set is an aftermarket option made for select Hamilton Beach TrueAir compact air purifiers, with two H13 True HEPA filters and four activated-carbon pre-filters. Its main strengths are fine-particle filtration, odor-control support, and a multi-filter package, but you need to confirm your purifier model before ordering. This review explains the fit, filtration, maintenance, limitations, and value so you can decide whether it matches your setup.
Quick Verdict
Rating: 8/10, Recommended with caveats
Best For: Owners of compatible Hamilton Beach TrueAir 04383, 04384, 04385, or 04386 air purifiers who want an aftermarket H13 HEPA and carbon pre-filter set.
Bottom Line: The PUREBURG set combines two H13 True HEPA filters with four activated-carbon pre-filters in one replacement package. Its biggest limitation is compatibility, so you should verify your purifier model and understand that this is not the genuine Hamilton Beach OEM filter before buying.

What Is the PUREBURG 990051000 Filter Set?
The PUREBURG 990051000 is an aftermarket replacement filter set designed for several Hamilton Beach TrueAir compact air purifiers. It is not the genuine Hamilton Beach OEM permanent filter. Instead, it gives you two H13 True HEPA filters plus four activated-carbon pre-filters in one package.
The HEPA portion is intended to capture fine airborne particles passing through the purifier, while the carbon pre-filter provides an additional layer for larger debris and helps reduce common household odors and some airborne chemical odors. This combination makes the set most relevant if you want particle filtration and odor-control support from the same replacement bundle.
The package is specifically marketed for Hamilton Beach TrueAir models 04383, 04384, 04385, and 04386. That model-specific fit is important because an air filter that is close in size but does not seat correctly can allow air to bypass the filter media.
Before You Buy: Check the model number printed on your Hamilton Beach air purifier before ordering. This PUREBURG set is an aftermarket compatible product, not an OEM Hamilton Beach filter, and it should not be purchased only because the 990051000 number looks familiar.
Who Should Buy It?
Best For
- You own a compatible Hamilton Beach TrueAir 04383, 04384, 04385, or 04386 purifier.
- You want both H13 HEPA filters and activated-carbon pre-filters in one package.
- You prefer a tool-free aftermarket replacement instead of buying an OEM filter.
Skip If
- Your purifier model is not specifically listed as compatible.
- You want only a genuine Hamilton Beach OEM replacement part.
- You expect an air filter to treat allergies, asthma, or another medical condition.
Filtration Performance: H13 HEPA and Activated Carbon
The main filtration claim is straightforward: PUREBURG lists its H13 True HEPA media as capturing 99.97% of PM2.5 particles down to 0.3 microns. For you, that means the filter is designed to trap fine particles such as dust and other common airborne particulates as air passes through the purifier.
The set is also listed with a MERV 17 rating. MERV and HEPA classifications are different rating systems, so you should treat the manufacturer or seller’s MERV listing as an additional product specification rather than assuming the two ratings are interchangeable.
Air-purifier performance still depends on more than filter media. Proper fit, fan airflow, filter condition, room conditions, and how often you run the purifier all influence how much airborne material actually passes through the filter.
What the Carbon Pre-Filters Add
The four activated-carbon pre-filters serve a different job from the HEPA layer. They help catch larger debris such as pet hair and dander before it reaches the main filter and are intended to help reduce common household odors, smoke odors, and some VOC-related odors.
Carbon filtration should not be treated as complete removal of every gas or chemical. The amount of carbon, airflow, exposure level, and age of the filter all affect odor performance. If odor control is your main reason for buying, replacing or maintaining the carbon layer when it becomes loaded is especially important.
Fit and Compatibility
PUREBURG lists this filter set as compatible with Hamilton Beach TrueAir 04383, 04384, 04385, and 04386 compact air purifiers and identifies 990051000 as the compatible replacement part number. That is more useful than choosing a filter by dimensions alone.
The set is listed at approximately 12 x 5 x 3 inches. Even with dimensions available, your purifier model number should be your first fit check because housings, frames, and filter-retention systems can differ.
If your purifier has a model suffix or looks different from the units listed for this replacement, compare the original filter number and your owner’s documentation before ordering. Do not trim, bend, or force the HEPA frame to make an incompatible filter fit.
Pro Tip: Take a photo of the model label and your current filter before ordering. You can compare the purifier model, filter orientation, frame shape, and 990051000 part reference without opening the purifier again.
How to Install and Maintain Your PUREBURG Filters
Installation is designed to be tool-free. Before you begin, turn the purifier off and follow the appliance instructions for opening the filter compartment. Remove the replacement filter from its plastic packaging before placing it into the purifier.
Install the H13 HEPA filter and carbon pre-filter in the correct orientation for your TrueAir model. The filter should sit normally in the housing without being crushed, folded, or forced into place. Close the purifier only after checking that the filter and cover are seated correctly.
Monthly Filter Care
PUREBURG’s product guidance recommends removing the filter about once a month and cleaning it gently with a soft brush or vacuum. Gentle cleaning can remove surface dust and debris that would otherwise restrict airflow.
Avoid treating that instruction as permission to wash the HEPA or carbon media. The product information does not support washing the filters, and moisture can damage filtration media or reduce the effectiveness of activated carbon.
When Should You Replace It?
The verified product information says to replace the filters regularly but does not establish one universal replacement interval for every household. Filter life changes with purifier run time, dust levels, pets, smoke, cooking odors, and other indoor conditions.
Inspect the filters during monthly maintenance. If they remain heavily loaded after gentle cleaning, airflow is noticeably restricted, odors return quickly, or your purifier’s instructions call for replacement, it is reasonable to install a fresh set.
How It Performs in Real Use
For Daily Household Use
For normal day-to-day operation, the combination of HEPA media and a carbon pre-filter addresses two common air-purifier jobs. The HEPA layer targets fine particles, while the pre-filter catches larger debris and provides some odor-control support.
The two-filter package is also useful if you prefer having a replacement available rather than ordering a single filter each time the current one reaches the end of its useful life.
For Homes With Pets
The carbon pre-filter can catch larger material such as pet hair and dander before it reaches the main HEPA layer. That can help keep larger debris from loading the HEPA surface as quickly.
You may need to inspect and gently clean the filter more often in a home with several pets or visible airborne hair. The product should still be used as an air-filtration tool rather than as a substitute for normal cleaning and source control.
For Odor-Prone Rooms
The activated-carbon layer gives this set an advantage over a particle-only filter when common household odors are part of the problem. It can be useful around routine cooking smells, pet odors, and similar indoor sources.
Carbon has a limited adsorption capacity, so odor performance can weaken as the media becomes saturated. Strong or hazardous fumes require proper ventilation and source removal rather than relying only on an air purifier.
For Long-Term Maintenance
The monthly brush-or-vacuum recommendation gives you a simple maintenance routine. Regular inspection also helps you spot a damaged frame, excessive loading, or a pre-filter that is no longer doing its job effectively.
Because this is an aftermarket filter, buyers who prioritize original-equipment construction and manufacturer-specific fit assurance may still prefer the genuine Hamilton Beach replacement instead.
Common Mistakes to Avoid
- Ordering by appearance alone: Verify the purifier model and compatible part number before buying.
- Leaving the plastic wrap on: Remove all shipping packaging before installation.
- Forcing the filter into place: Stop if the frame does not seat naturally in the purifier.
- Assuming carbon lasts indefinitely: Carbon loses effectiveness as it adsorbs odors and contaminants.
- Using aggressive cleaning methods: Follow the gentle brush or vacuum guidance rather than washing or scrubbing the media.
- Treating filtration as medical treatment: An air purifier can reduce certain airborne particles, but it should not replace medical care or professional advice.
Pros and Cons
Pros
- Includes two H13 True HEPA filters plus four activated-carbon pre-filters.
- Listed for four Hamilton Beach TrueAir compact purifier models.
- HEPA media is listed to capture 99.97% of PM2.5 particles down to 0.3 microns.
- Carbon pre-filters add larger-particle and household-odor control.
- Tool-free installation and simple monthly maintenance guidance.
Cons
- Limited to specific Hamilton Beach TrueAir models.
- It is an aftermarket replacement, not the genuine Hamilton Beach OEM filter.
- No single replacement interval fits every home, so you need to inspect filter condition over time.
Is It Worth the Price?
The PUREBURG 990051000 set can offer strong value for the price if your purifier is compatible and you specifically want both HEPA and activated-carbon filtration components. You receive two main filters and four pre-filters, which gives you multiple replacement components in one purchase.
The value is less clear if you prefer genuine OEM parts. Hamilton Beach sells an original 990051000 permanent replacement filter, so buyers who prioritize an original manufacturer part may consider the OEM route more appropriate even if the filter design and package format differ.
For an aftermarket buyer, PUREBURG makes the most sense when compatibility, H13 filtration, and the included carbon pre-filters matter more to you than having a Hamilton Beach-branded replacement.
How It Compares to Alternatives
The clearest alternative is the genuine Hamilton Beach 990051000 permanent filter. That option comes from the purifier manufacturer and is aimed at buyers who want an OEM replacement. PUREBURG instead offers an aftermarket H13 HEPA package with additional activated-carbon pre-filters.
You can also find other third-party 990051000-compatible filter bundles with different HEPA and pre-filter quantities. Those alternatives may make sense if you want a larger multi-pack, but quantity alone should not replace model verification. PUREBURG is most appealing if its two-HEPA and four-carbon configuration matches how you plan to maintain your purifier.
Frequently Asked Questions
Which Hamilton Beach air purifiers fit the PUREBURG 990051000 filters?
PUREBURG lists the set as compatible with Hamilton Beach TrueAir models 04383, 04384, 04385, and 04386. Check the model label on your purifier before ordering because similar-looking TrueAir units may use different filters.
How many filters are included in the set?
The reviewed configuration includes two H13 True HEPA filters and four activated-carbon pre-filters. That gives you six filter components in total.
Is PUREBURG 990051000 an OEM Hamilton Beach filter?
No. PUREBURG is an aftermarket compatible replacement. Hamilton Beach separately offers its own genuine 990051000 permanent filter, so choose the OEM version if original-manufacturer parts are a priority for you.
Can you wash the PUREBURG HEPA or carbon filters?
The verified product guidance supports gentle monthly cleaning with a soft brush or vacuum. It does not instruct you to wash the filter media, so avoid soaking or rinsing it unless current manufacturer instructions specifically say otherwise.
How often should the filters be replaced?
PUREBURG advises regular replacement but does not provide one verified lifespan that applies to every household. Check the filter condition during monthly maintenance and follow your purifier and filter instructions when deciding when replacement is needed.
Do the activated-carbon pre-filters help with odors?
They are designed to help reduce common household odors, smoke odors, and some VOC-related odors while catching larger debris. Their effectiveness can decrease as the carbon becomes loaded, so they should not be treated as permanent odor-removal media.
Can this filter treat allergies or asthma?
The HEPA filter is designed to capture airborne particles passing through the purifier, which may reduce some dust and similar airborne material in the room. It is not a medical treatment for allergies or asthma, so you should follow medical guidance for health concerns.
The Bottom Line
The PUREBURG 990051000 Replacement True HEPA Filter Set is a sensible aftermarket choice if you own a listed Hamilton Beach TrueAir model and want two H13 HEPA filters plus four activated-carbon pre-filters in one package. Its strongest points are the combined particle and odor filtration approach, simple installation, and useful multi-filter bundle, while its main limitation is that it is not an OEM filter and is suitable only for specific purifier models.
If your model matches and aftermarket filtration suits your needs, it earns our Recommended with caveats verdict. If you require a genuine Hamilton Beach filter or your purifier is not one of the supported models, choose a different replacement.
