The Levoit LV-H132 and LV-PUR131 are both three-stage purifiers from the same brand, but they are built for very different spaces. The LV-H132 is a compact personal unit meant for a desk, nightstand or tiny room. The LV-PUR131 is a larger, heavier unit intended for a full bedroom or similar room, with auto mode and a timer. Choosing between them is mostly about how much air you need to move.
LV-H132 details below come from Levoit’s own product page. LV-PUR131 details come from a third-party review, because we could not confirm the full specification on a current Levoit page, and this model may be discontinued or replaced. We have not tested these products ourselves, and we do not list prices, so confirm current specifications and availability.
LV-H132 fits
- Desks, nightstands and very small rooms
- Easy moving between spaces
- Quiet on its lowest setting
LV-PUR131 fits
- A full bedroom or similar room
- Buyers who want auto mode and a timer
- More airflow with a larger filter
Key Takeaways
- The LV-H132 is a personal-space purifier: Levoit lists 35 CFM CADR and 54 sq ft at 4.8 air changes per hour.
- The LV-PUR131 is a room-sized unit: a reviewer reports roughly 135 CFM CADR and a rated area up to about 322 sq ft.
- Compare room-size claims on the same air-change basis before deciding, because 1 ACH and 4.8 ACH figures are not equivalent.
- Filter replacement, noise at your usual speed and current availability matter more than feature lists.
- LV-PUR131 figures here are third-party and the model may be discontinued, so verify on current listings.
A Simple Decision Checklist
Start with the room. Measure length and width, multiply for square feet, and note the ceiling height. Next, decide how fast you want the air cleaned: a quiet background level or a stronger setting for allergy or smoke days. Then match smoke CADR to roughly two-thirds of floor area for standard eight-foot ceilings.
After that, compare the noise you will tolerate at night, the cost and supply of replacement filters, and any features you will actually use, such as a timer or night light. Finally, check that the exact model is still sold and read the current manual before purchase. If any key figure differs from what is written here, trust the manufacturer’s current page over this comparison.
Buying a purifier is only one step. Keeping windows closed during high outdoor pollution, vacuuming regularly and controlling sources such as smoking and unvented combustion will do as much for indoor air as the device itself.
Air Purifiers to Compare
The table below lists purifiers from our affiliate partner. Compare smoke CADR, room size ratings and filter details across models, and check Levoit’s pages for current options.
Comparing the Two on Capacity
The LV-H132’s 54 square feet at 4.8 air changes per hour is about the size of a closet-sized room or a small desk area, which is why it is described as personal. Its 259 square feet at 1 air change per hour looks larger but means the air is cycled only once an hour.
The LV-PUR131’s figure of about 322 square feet is a much larger rated area. Using the AHAM rule that smoke CADR should be about two-thirds of floor area, a CADR of 135 corresponds to a room of about 200 square feet at 4.8 air changes per hour. That is a realistic target for a bedroom.
At a Glance
The table below summarizes the published and reported figures. Confirm current numbers.
| Factor | LV-H132 (Levoit page) | LV-PUR131 (reviewer figures) |
|---|---|---|
| CADR | 35 CFM | About 135 or more |
| Room size | 54 sq ft at 4.8 ACH | Up to about 322 sq ft |
| Noise | About 25 to 50 dB | About 39 dB sleep, 58 dB high |
| Weight | About 6 lbs | About 15.8 lbs |
| Features | Timer, night light, display off | Auto mode, timer, touch display |
What Levoit Lists for the LV-H132
Levoit’s page lists a CADR of 35 CFM, with a room size of 259 square feet at 1 air change per hour or 54 square feet at 4.8 air changes per hour. It has a three-stage filter with a pre-filter, a main filter for fine particles, pollen and dander, and an activated carbon layer. Noise is listed from about 25 dB on the lowest speed to 50 dB at maximum.
It measures about 8 by 8 by 12.6 inches, weighs about 6 pounds and draws 28 watts. It has a sleep mode, three timer settings, an LED display, a night light with two brightness levels and a display-off function. Levoit describes it as ozone-free. Filter replacement intervals are not stated on the page, so check the manual.
What a Review Reports for the LV-PUR131
A Modern Castle review describes the LV-PUR131 as a three-stage unit with a pre-filter, a particulate filter and activated carbon, rated for rooms up to about 322 square feet, with a CADR figure of 135 or more, noise of about 39 dB in sleep mode and about 58 dB at the highest setting. It is about 15.8 pounds, has auto mode, sleep mode, a timer and touch controls, and no Wi-Fi. The reviewer cites a manufacturer estimate of replacing the filter about every six months and a two-year limited warranty.
These are third-party figures and the unit may have been updated or discontinued, so verify on Levoit’s site and retailer pages.
Why These Two Are Not Direct Rivals
Most comparison posts assume two products compete for the same buyer. This pair mostly does not. The LV-H132 is small enough to sit on a desk and is rated for about 54 square feet at a higher air-change rate. The LV-PUR131 is a floor or large-table unit with a much bigger filter and a rated area several times larger. If you are deciding between them, you are really deciding whether you need personal-zone cleaning or whole-room cleaning.
A useful test is to measure the space you actually sit or sleep in. If the answer is a desk, a reading chair or a small nursery corner, the compact unit may be a sensible fit. If the answer is a standard bedroom, the larger unit is the more realistic starting point.
Reading Room-Size Claims Correctly
Manufacturers often list two room sizes: a large number at one air change per hour and a smaller number at 4.8 air changes per hour, which is the level associated with the AHAM smoke-CADR rule. Levoit lists both for the LV-H132, which is why its page shows 259 square feet and 54 square feet side by side. Neither is wrong, but they describe different cleaning speeds.
If your goal is noticeably faster cleaning, such as for allergy season or smoke events, the 4.8 air-change figure is the more demanding and more useful one. The 1 air-change figure only tells you the unit can turn the room’s air over once an hour.
Noise and Where You Will Run It
Noise ratings are measured at specific speeds. The LV-H132 lists about 25 dB at its lowest setting, which suits a nightstand. The reviewer figure for the LV-PUR131 is about 39 dB in sleep mode, which is still modest, rising to around 58 dB at the top speed. A purifier that is too weak for the room tends to be run on high, so a larger unit used on a low setting can end up quieter in practice than a small unit pushed to maximum.
Decide which speed you will really use for most of the day and compare those numbers, not the maximum.
Filters and Ongoing Care
Both models use a three-stage approach with a pre-filter, a particle filter and activated carbon. The pre-filter catches larger dust and hair and protects the main filter. Activated carbon helps with some odors but is not a substitute for ventilation or removing the source of strong fumes.
Levoit’s LV-H132 page does not state a replacement interval, and the LV-PUR131 reviewer cites about six months. Check the manual for your actual model and look at the cost and availability of replacement filters before you buy, since this is the main recurring expense.
Placement Tips for Either Model
Give the unit a few inches of clearance so intake and output are not blocked. Keep it off thick carpet or soft surfaces where possible and avoid placing it directly behind furniture. For a bedroom, put it where air can circulate around the bed instead of in a corner facing a wall.
Keep doors closed while it runs if you want the stated room size to apply, and run it continuously rather than only for short bursts, since steady operation holds particle levels down.
When to Skip Both
If you need to clean an open-plan living area or a room larger than about 300 square feet, neither unit is a good fit. A larger CADR model, or more than one unit, is the better route. If someone in the home has a serious respiratory condition, a purifier should be one part of a plan that includes your clinician’s advice. This post gives general information only and is not medical advice.
How to Choose
- Size by smoke CADR for your room.
- Convert room size claims to the same air-change basis.
- Check filter life and replacement cost.
- Check noise at the speed you will use.
- Avoid ozone generating or ionizer modes; the EPA advises against ozone-emitting air cleaners.
Do
- Match the unit’s rated coverage to your room first
- Run it consistently, not only when the air feels bad
- Leave space around the unit for airflow
- Replace filters on the maker’s schedule
Don’t
- Do not buy on looks or price alone
- Do not block the intake or exhaust
- Do not skip filter changes
- Do not expect a purifier to fix every source of pollution
Honest Limits
- This guide uses manufacturer information and public guidance from the EPA and AHAM, not our own lab tests.
- Features and room ratings change between model years, so confirm on the listing before you buy.
- A purifier is not a medical device and does not replace medical advice or treatment.

Frequently Asked Questions
Is the LV-H132 enough for a bedroom?
It depends on the bedroom size and your goals. Levoit lists 54 square feet at 4.8 air changes per hour and 259 square feet at 1 air change per hour, so it is better suited to a personal zone or small space than a standard bedroom if you want faster cleaning.
What does CADR mean?
CADR is clean air delivery rate, a measure of how much filtered air a purifier delivers. A higher CADR means faster cleaning of a given room.
Do these purifiers make ozone?
Levoit describes the LV-H132 as ozone-free. The EPA advises against air cleaners that deliberately emit ozone, so check the specifications of any model you consider.
How often should I change the filter?
Follow the manual for your model. A reviewer cites about six months for the LV-PUR131, and the LV-H132 page does not state an interval, so confirm before buying.
Are the LV-PUR131 specs reliable?
They come from a third-party review and may not match current production. Verify on current retailer or Levoit pages.
Bottom Line
The LV-H132 is a personal-space unit and the LV-PUR131 is a room-sized unit; their capacities differ by roughly four times.
Size for your space, verify current specs and availability and plan your filter replacements.
