Replacement filters can look almost identical online, but a small compatibility mistake can leave you with a filter that does not fit your purifier. The Flintar LV-H133-RF Replacement Filter is a third-party replacement made for the Levoit LV-H133 Tower Air Purifier, with a three-stage design that combines a pre-filter, an H13-grade main filter, and activated carbon. It is a practical choice if you want a compatible LV-H133 filter without buying the Levoit-branded OEM cartridge. The main limitation is just as important: this listing is for the LV-H133 size, so you should confirm the exact model number on your purifier before ordering.
Quick Verdict
Rating: 8/10, Recommended with caveats
Best For: Levoit LV-H133 owners who want a third-party 3-stage replacement filter with activated carbon.
Bottom Line: The Flintar LV-H133-RF offers the key filtration layers and fit needed for the LV-H133, plus a stated 6-8 month replacement interval. Its biggest tradeoff is that it is not a genuine Levoit filter and has limited compatibility outside the listed purifier model.
Key Takeaways
- The Amazon listing identifies this product as a Flintar LV-H133-RF compatible replacement, not a genuine Levoit-branded filter.

What Is the Flintar LV-H133-RF Replacement Filter?
The Flintar LV-H133-RF is a cylindrical replacement cartridge sold for the Levoit LV-H133 Tower Air Purifier. It is manufactured by Flintar LLC and uses a pleated, three-stage filtration design. The package contains one filter, so it is a direct replacement item rather than a multi-pack.
The key distinction is branding. This is not the genuine Levoit LV-H133-RF filter sold by Levoit. It is a Flintar-compatible replacement that is sized for the LV-H133. That makes it most relevant to buyers who are comfortable using a third-party filter but still want the same basic combination of large-particle capture, fine-particle filtration, and activated carbon odor control.
Who Should Buy It?
Best For
- Levoit LV-H133 owners who need a one-filter replacement.
- Homes where dust, hair, pet dander, cooking odors, or smoke particles are common concerns.
- Buyers who prefer a third-party LV-H133-compatible filter rather than the Levoit-branded OEM option.
Skip If
- Your purifier is not the LV-H133 or another model explicitly listed as compatible.
- You only want a genuine Levoit-branded replacement filter.
- You need a washable or permanent filter instead of a replaceable cartridge.
Before You Buy: Check the model label on your purifier before ordering. The Amazon listing says this filter is designed for the Levoit LV-H133 and does not fit other models, so a similar-looking Levoit purifier may still use a different filter size.
Top Features of the LV-H133 Replacement Filter
Three-Stage Filtration
The first layer is a fine pre-filter that catches larger debris such as hair, lint, dust, and pet fur before it reaches the denser inner media. This helps keep larger particles from loading the main filter as quickly during normal use.
The H13-grade main filter is the fine-particle stage. Flintar states that it captures 99.97% of harmful airborne particles down to 0.3 microns, including fine dust, pollen, pet dander, and smoke particles. That claim describes filtration efficiency at the filter level, not a guarantee that every room will reach a specific air-quality target.
Activated Carbon for Household Odors
The activated carbon stage is designed to absorb or reduce common household odors and gaseous pollutants, including cooking smells, pet odors, smoke, fumes, and VOCs. This layer is useful when your reason for running the LV-H133 is not only visible dust but also stale or persistent indoor odors.
Activated carbon has a finite capacity, so odor control can weaken before the filter looks heavily dirty. If odors begin returning sooner than expected, your environment, purifier run time, and pollution load may justify replacing the cartridge earlier than the general 6-8 month schedule.
Made for the LV-H133 Form Factor
The filter measures about 9.9 x 9.9 x 11.25 inches and uses a pleated construction. The listing identifies it as a direct replacement for the Levoit LV-H133 Tower Air Purifier. Correct fit matters because gaps around the filter can allow air to bypass the filtration media instead of passing through it.
How the Filtration System Works for Better Air Quality
Air drawn into the purifier passes through the filter layers in sequence. Larger hair, lint, and dust are stopped first. The main filter then targets smaller airborne particles, while the activated carbon layer addresses odors and certain gaseous contaminants.
This layered approach is more useful than relying on one filter medium to do every job. The pre-filter handles visible debris, the main filter handles fine particles, and carbon handles odors. Your actual room results will still depend on purifier placement, fan speed, room size, how often you run the unit, and how much pollution is being generated indoors.
Setup Tips Before First Use
Turn the purifier off and unplug it before opening the filter compartment. Remove the old cartridge, unwrap the new filter completely, and place it in the housing in the same orientation specified by the purifier instructions. Close the cover securely before restoring power.
After replacement, check that the cover is seated correctly and that the purifier runs without unusual vibration or rubbing sounds. If the purifier has a filter-life indicator, follow the LV-H133 manual for the correct reset procedure rather than assuming the indicator will reset automatically.
Pro Tip: Write the installation month on a small note near the purifier or add a calendar reminder for six months later. That gives you a simple starting point for checking the filter without relying only on memory.
Tips for Maintaining Your Filter
Flintar recommends replacing the LV-H133-RF every 6-8 months for optimal performance. That interval is a guideline, not a fixed deadline. A home with pets, frequent cooking, smoke exposure, construction dust, or long purifier run times can load a filter faster than a cleaner, lightly used room.
Check the filter periodically for heavy dust loading, reduced airflow, persistent odor return, or an unusually strained purifier sound. Keep the purifier’s exterior intake and surrounding area clean according to the LV-H133 manual. Do not wash or soak the main filter media unless the product instructions specifically say it is washable.
How It Performs in Real Use
For Homes With Pets
The combination of a pre-filter, fine-particle stage, and activated carbon is well matched to the mix found in pet households. The outer stage catches fur and larger debris, the main filter targets airborne dander and dust, and carbon helps with pet-related odors. You may need to inspect the filter more often if shedding is heavy.
For Kitchens and Odor-Prone Rooms
The carbon layer gives this filter an advantage over particle-only media when cooking smells are part of the problem. It can help reduce odors that circulate through the purifier, but it is not a substitute for a range hood, exhaust fan, or ventilation when cooking produces smoke or strong fumes.
For Dust and Seasonal Airborne Particles
The H13-grade main filter is designed to capture fine particles that pass through the pre-filter. That makes it useful during dusty periods or when pollen and outdoor particles enter the home. For best results, keep doors and windows managed appropriately and run the purifier at a setting that moves enough room air through the filter.
For Long-Term Ownership
The main ownership task is predictable filter replacement. The one-filter package and 6-8 month guidance make the maintenance cycle easy to understand. The ongoing tradeoff is that you will need to budget for recurring cartridges, and third-party filter density or airflow can feel different from an OEM filter.
Compatibility and Safety
Compatibility is the most important safety and performance check with any replacement filter. Use this cartridge only in a purifier model listed as compatible, and follow the purifier manufacturer’s instructions for access, orientation, cover installation, and filter-indicator reset. Never force a filter into a housing that does not match.
An air purifier can reduce airborne particles that pass through its filter, but it does not replace source control, ventilation, smoke alarms, carbon monoxide alarms, or professional help for indoor environmental hazards. If you have a health condition affected by indoor air, use your clinician’s guidance rather than relying on a replacement filter as treatment.
What’s Covered by the Warranty?
The current Amazon product details list a 90-day manufacturer’s warranty from the purchase date. Warranty coverage can depend on the seller and the reason for the claim, so keep your order information and review the current warranty terms shown on the product page when you buy.
Do not assume the Levoit purifier warranty automatically covers a third-party filter. If preserving purifier warranty coverage is a priority for you, check Levoit’s current warranty terms before choosing between an OEM and compatible replacement.
Pros and Cons
Pros
- Designed specifically for the Levoit LV-H133 form factor.
- Three-stage filtration combines large-particle, fine-particle, and odor-control media.
- H13-grade main filter carries a 99.97% down-to-0.3-micron filtration claim.
- Activated carbon targets cooking, pet, smoke, and other household odors.
- Clear 6-8 month replacement guidance simplifies routine maintenance.
Cons
- It is a Flintar-compatible filter, not a genuine Levoit OEM filter.
- Compatibility is limited, so it is a poor choice if your purifier is not the LV-H133 or another explicitly listed model.
- The filter is a recurring consumable and may need replacement sooner in high-dust or high-odor homes.
What Buyer Feedback Suggests
Buyer feedback on the current Amazon listing is generally positive, which supports the idea that many LV-H133 owners find the Flintar filter usable as a compatible replacement. The most useful feedback to watch is not the headline rating but comments about fit, airflow, odor control, and purifier noise after installation.
Third-party filters can feel different from OEM filters because media density and construction may vary. If your purifier becomes noticeably louder, airflow drops sharply, or the cartridge does not seat correctly, recheck installation and model compatibility instead of assuming the behavior is normal.
Is It Worth the Price?
The Flintar LV-H133-RF makes the most sense as a value-focused alternative to the genuine Levoit replacement. You still get the filtration structure most buyers expect for this purifier: a pre-filter, an H13-grade main filter, and activated carbon. That combination gives you a practical reason to consider it beyond price alone.
Its value depends on your comfort with third-party consumables. If you mainly want correct LV-H133 fit and the stated three-stage filtration, it is worth considering. If you prioritize original-brand parts, documented OEM materials, or the least uncertainty about purifier compatibility, paying more for Levoit’s genuine replacement may be the better fit.
How It Compares to Alternatives
The clearest alternative is the genuine Levoit LV-H133-RF replacement filter. Levoit lists its own LV-H133-RF as compatible only with the LV-H133 and uses a similar three-stage approach with a pre-filter, main filter, and activated carbon. The OEM option is better if brand authenticity matters most, while Flintar is aimed at buyers comfortable with a compatible third-party cartridge.
You can also find third-party choices such as the isinlive LV-H133 replacement filter in multi-pack configurations and the PUREBURG LV-H133-RF replacement filter. Those can be worth comparing if package quantity or replacement cost per filter matters to you. The Flintar option is simplest if you want a single replacement cartridge with clearly stated LV-H133 fit.
Frequently Asked Questions
Is the Flintar LV-H133-RF a genuine Levoit filter?
No. The Amazon listing identifies the brand as Flintar and the manufacturer as Flintar LLC. It is a compatible replacement for the Levoit LV-H133, not a Levoit-branded OEM cartridge.
Which air purifier does this replacement filter fit?
It is specifically listed for the Levoit LV-H133 Tower Air Purifier. The listing also mentions MetaAir compatibility, but you should match the exact model and dimensions before ordering.
How often should you replace the LV-H133-RF filter?
Flintar recommends replacement every 6-8 months for optimal performance. Heavy dust, pets, smoke, frequent cooking, or long daily run times can shorten that interval.
Can you wash and reuse this filter?
Treat it as a replaceable cartridge rather than a washable permanent filter. Do not soak or wash the main filter media unless Flintar’s current instructions specifically allow it, because moisture can damage filter media and carbon.
Does the filter help with pet and cooking odors?
Yes, odor control is one of the stated purposes of the activated carbon stage. It is designed to reduce household odors from pets, cooking, smoke, and related fumes as air passes through the purifier.
What is included in the package?
The current listing specifies one 360-degree three-stage replacement filter. It is not a two-pack, so check the package quantity if you are comparing the total cost with multi-pack alternatives.
What warranty does the Flintar LV-H133-RF include?
Amazon’s current product details list a 90-day manufacturer’s warranty from the purchase date. Review the current seller and warranty information at checkout because policies can change.
Who should skip this replacement filter?
Skip it if your purifier is a different model, if you need a washable filter, or if you only want genuine Levoit parts. In those cases, verify the exact OEM part number for your purifier before buying.
The Bottom Line
The Flintar LV-H133-RF is a sensible choice for LV-H133 owners who want a third-party replacement with three-stage filtration, activated carbon, and a clear 6-8 month maintenance schedule. Its main strength is the feature set and model-specific fit, while its main limitation is that it is not a genuine Levoit filter and should not be assumed to fit other Levoit models. Choose it if those tradeoffs fit your priorities, and choose the OEM Levoit filter if original-brand parts matter more to you.
