Replacing an LV-PUR131 filter sounds simple, but the biggest buying mistake is assuming every compatible filter is a genuine Levoit part. The Smilyan LV-PUR131 Replacement Filter set linked in this review is a third-party option made for the Levoit LV-PUR131 and LV-PUR131S. It combines H13 True HEPA filtration, activated carbon, and a multi-filter package intended to reduce replacement hassle. The main tradeoff is that you are choosing a compatible filter rather than Levoit’s genuine replacement, so fit, filter-life tracking, and manufacturer support deserve extra attention.
Quick Verdict
Rating: 8/10, Recommended with caveats
Best For: LV-PUR131 or LV-PUR131S owners who want a multi-filter third-party replacement set.
Bottom Line: The package gives you H13 True HEPA and activated carbon filtration with enough filters for multiple replacement cycles. However, it is a Smilyan compatible product rather than a genuine Levoit filter, which matters if you prefer manufacturer-original parts and filter-life tracking designed around authentic filters.

What Is the Smilyan LV-PUR131 Replacement Filter Set?
This product is a third-party replacement filter package for two specific Levoit air purifier models: the LV-PUR131 and LV-PUR131S. It is not the air purifier itself, and it should not be confused with Levoit’s genuine LV-PUR131-RF filter.
The set uses three filtration functions. A preliminary layer handles larger airborne particles, the H13 True HEPA portion targets finer particles, and the activated carbon section is designed for household odors. The seller lists two HEPA filters and two activated carbon filters in the package, giving you more than one replacement cycle without immediately ordering another set.
Before You Buy: Check the model label on your purifier before ordering. This filter set is intended for the LV-PUR131 and LV-PUR131S, and the linked ASIN is a Smilyan compatible replacement rather than a genuine Levoit filter.
Who Should Buy It?
Best For
- Owners of a Levoit LV-PUR131 or LV-PUR131S who need replacement filters.
- Buyers who prefer a multi-filter package for future replacement cycles.
- Households that want HEPA particle filtration plus activated carbon odor control.
Skip If
- You require a genuine Levoit-branded replacement filter.
- Your purifier is not an LV-PUR131 or LV-PUR131S.
- You want filter-life monitoring specifically calibrated around genuine Levoit filters.
How the Three-Layer Filtration System Works
Preliminary Filtration
The first filtration stage is intended to catch larger material before air reaches the finer HEPA media. This helps keep hair, lint, and larger dust particles from loading the finer filter as quickly.
H13 True HEPA Filtration
The seller describes the HEPA portion as an H13 True HEPA filter capable of capturing 99.97% of particles as small as 0.3 microns. That specification is useful if your main goal is reducing fine airborne material such as dust and pollen passing through the purifier.
The filtration claim applies to particles passing through the filter media. Actual room performance also depends on the purifier itself, airflow, room conditions, filter installation, and how heavily the filter has been used.
Activated Carbon for Odors
The separate activated carbon stage is aimed at odors rather than simply adding another particle-catching layer. The seller specifically lists odors associated with pets, smoking, and cooking.
Activated carbon can be useful in rooms where odor control matters, but no replacement filter can eliminate every source of indoor odor. Persistent odors may still require cleaning, ventilation, or removal of the source.
Compatibility and Fit
Compatibility is the most important specification to check before buying this set. The seller identifies the product as compatible with Levoit LV-PUR131 and LV-PUR131S air purifiers. Do not buy it based only on the general shape of your current filter.
Look at the model label on your purifier and confirm the complete model number. Similar-looking Levoit purifiers may use different filter sizes and designs.
Pro Tip: Take a photo of your purifier’s model label before shopping for replacement filters. Comparing the photo with the compatibility information on the product page is faster and safer than relying on memory.
How It Performs in Real Use
For Everyday Dust and Pollen
The combination of preliminary and H13 True HEPA filtration is the main reason to consider this set for routine purifier maintenance. When properly installed in a compatible purifier, the filter media is designed to capture both larger debris and much finer airborne particles moving through the unit.
For Homes With Pets
Pet households can benefit from both filtration stages. Larger hair and debris are handled earlier in the filtration path, while the activated carbon section is intended to reduce pet-related odors. Heavy pet-hair environments may load filters faster, so inspect performance rather than assuming every household will get exactly six months from a set.
For Cooking and Smoke Odors
The carbon component is the relevant feature when cooking smells or smoke odors are a concern. It adds an odor-control function that a particle-only filter would not provide. Strong or continuous odor sources can still overwhelm filter media, so source control and ventilation remain important.
For Long-Term Ownership
The multi-filter package is convenient if you expect to keep an LV-PUR131-series purifier in service. With two HEPA filters and two carbon filters listed in the package, you can keep another replacement cycle available instead of waiting until the current filter is exhausted before ordering again.
Setup and Maintenance Tips
Turn the purifier off and unplug it before opening the filter compartment. Remove the used filter media carefully so accumulated dust is not spread around the room, then remove all protective packaging from the replacement filters before installation.
Install the filters in the orientation required by your purifier’s instructions and make sure the back cover closes correctly. A poorly seated filter can interfere with airflow or prevent the housing from closing as intended.
The seller recommends replacement about every six months. Treat that as a guideline rather than a guarantee. Homes with more dust, pet hair, smoke, or continuous purifier use may need earlier replacement.
Do not assume replacement filter media can be washed. Follow the instructions supplied with the filter set and the purifier manual before using water, cleaners, or other liquids on filter media.
Compatibility and Safety
This filter set should be used only in the purifier models for which it is specified. Forcing an incorrectly sized filter into another purifier can interfere with fit and airflow.
Levoit states that the filter-life indicator and built-in filter algorithm in its LV-PUR131 system are designed around authentic filters. Because this Smilyan set is a third-party replacement, an electronic reminder should not be treated as a direct measurement of the physical condition of the replacement media.
Air purification can reduce certain airborne particles and odors, but an air purifier or replacement filter is not a treatment for a medical condition. Follow the purifier manufacturer’s operating instructions and seek appropriate professional advice for health concerns.
Pros and Cons
Pros
- Designed specifically for LV-PUR131 and LV-PUR131S compatibility.
- Seller specifies H13 True HEPA filtration at 99.97% for 0.3-micron particles.
- Activated carbon adds odor-control capability for pets, smoke, and cooking.
- Package includes two HEPA filters and two activated carbon filters.
- Multi-stage design handles both larger debris and finer airborne particles.
Cons
- It is a third-party Smilyan filter set rather than a genuine Levoit replacement.
- Compatibility is limited to the specified LV-PUR131-series models.
- Actual replacement intervals can vary with dust, pets, smoke, and usage.
Is It Worth the Price?
The strongest value argument is the package quantity. Instead of getting only one replacement cycle, the listing specifies two HEPA filters and two activated carbon filters. That can make the set worth considering if you plan to keep the same purifier for an extended period.
The tradeoff is that value is not determined by quantity alone. Buyers who place a high priority on genuine Levoit parts, manufacturer-specific filter tracking, and first-party filter specifications may prefer paying for Levoit’s own LV-PUR131 replacement filter instead.
For buyers comfortable using a compatible third-party filter, the Smilyan set offers a practical combination of HEPA filtration, carbon odor control, and multiple replacements in one package.
How It Compares to Alternatives
The most direct alternative is the genuine Levoit LV-PUR131-RF replacement filter. Levoit’s version is designed specifically around its purifier and filter-life system, making it the better fit for buyers who prioritize first-party components. The Smilyan package makes more sense if your priority is receiving multiple compatible replacement filters in one purchase.
You can also find third-party options such as isinlive LV-PUR131-RF compatible filters. When comparing third-party sets, focus on the exact purifier compatibility, package contents, filtration claims, replacement instructions, and seller support rather than assuming every LV-PUR131-compatible filter is identical.
Where to Buy the Smilyan LV-PUR131 Filters
The Amazon listing linked in this review is the purchase reference for this specific Smilyan set. Before ordering, confirm that the product page still shows the same brand, package contents, and compatibility with your purifier model because marketplace listing details can change over time.
Frequently Asked Questions
Is this a genuine Levoit replacement filter?
No. The linked Amazon ASIN identifies Smilyan as the brand and manufacturer. It is a third-party replacement set designed to be compatible with selected Levoit purifiers.
Which Levoit air purifiers are compatible?
The listing specifies compatibility with the Levoit LV-PUR131 and LV-PUR131S. Check the model label on your purifier before ordering because similar Levoit models can use different filters.
How many replacement filters are included?
The seller listing states that the package includes two HEPA filters and two activated carbon filters. That provides two paired replacement cycles when the filters are used together as intended.
How often should the filters be replaced?
The seller recommends replacement about every six months. Actual life can vary with purifier use, dust levels, pets, smoke, and other indoor conditions, so inspect performance rather than relying only on the calendar.
Can these replacement filters be washed?
Do not assume the filter media is washable. Follow the directions supplied with the replacement set and your purifier manual before exposing the filters to water or cleaning liquids.
What does the activated carbon filter do?
The carbon section is intended to reduce common household odors, including smells associated with pets, smoking, and cooking. It complements the HEPA portion, which focuses on airborne particles.
Who should choose the genuine Levoit filter instead?
Choose the genuine filter if first-party components and Levoit’s own filter-life system are priorities for you. Levoit states that its filter-life indicator algorithm is designed around authentic replacement filters.
The Bottom Line
The Smilyan LV-PUR131 Replacement Filter set is worth considering if you own an LV-PUR131 or LV-PUR131S and want a multi-filter third-party package with H13 True HEPA and activated carbon filtration. Its biggest strength is the combination of filtration functions and multiple replacements, while its main limitation is that it is not a genuine Levoit filter. Buyers who want manufacturer-original parts should choose Levoit’s replacement instead.
