Compare Levoit P350-P vs Shark MAX HP202

Reviewers liked the stronger carbon stage for pet and household odors, with experts pointing to extra carbon and customers linking the pet-rated filter to cleaner-smelling air. The main caveat is that odor results depend on filter upkeep.

One expert-style review liked the charcoal-lined HEPA filter because it helped with odors.

Experts consistently describe the P350 as quick for its intended room size, with around five air changes per hour or a 12-minute exchange cycle. This supports small-room use more than whole-home cleaning.

Airflow gets credit for moving and circulating a lot of air quickly, and some users enjoy the upward flow. One expert noted that the diffuse top outlet is not meant to create a strong breeze.

Most reviewers say the P350 noticeably improves room air, especially in bedrooms, pet rooms, and small living spaces. A few users were disappointed when the unit was undersized for the room or did not relieve their symptoms.

Most reviewers said the unit improved air quality, cleaned rooms quickly, or worked well, though a smaller group reported weak performance or failures.

Sensor feedback was the most divided area: many liked the live readings, but repeated customers reported stuck 0%, unrealistic 100%, or humidifier-triggered readings.

Allergy feedback is mostly enthusiastic, with many users reporting less sneezing, congestion, itchy eyes, or pet-allergy irritation. One negative customer review said allergy symptoms became worse, so relief is not guaranteed.

Customers often reported allergy, breathing, asthma, or irritation relief, including homes with pets and dusty conditions.

App control is a clear weakness. Reviewers repeatedly point out that the P350 lacks app connectivity, scheduling through an app, and air quality readouts.

Auto mode is missing, and reviewers treat that as one of the main feature tradeoffs. Buyers have to choose fan speeds manually instead of letting the purifier respond to air quality.

Auto mode was praised for reacting to cooking, smoke, and pollutants, but several owners disliked ramping, cycling, or failure to reach stable readings.

Many owners describe easier breathing, fewer asthma or sinus issues, less congestion, and cleaner-feeling air after running the purifier. The strongest praise comes from pet-allergy and respiratory-irritant situations.

Build quality is generally viewed as solid, with praise for durable plastic, good fit and finish, and a well-made feel. One negative review felt the unit operated more cheaply than its price suggested.

Build impressions were positive where mentioned, including a customer who said the unit physically held up under an accidental fall.

Expert reviews view the CADR and fan power as strong for a compact purifier, especially in the under-230-square-foot range. It is not framed as a large-room machine.

The pet lock is appreciated by owners with pets or children, but it is not foolproof for every home. One cat owner said their kittens still managed to interfere with the controls.

Packaging and arrival condition receive a positive nod from a customer who felt the product was protected and arrived with care. There was no recurring complaint about damaged delivery.

One owner reported the unit worked fine immediately out of the box.

Controls are usually described as clear, simple, and easy to use. Customers especially liked the touch controls and straightforward top-panel layout.

The one expert comment on support was favorable, describing negative service feedback as rare and highlighting easy registration for extended warranty coverage.

Customer support evidence was negative, with one owner saying they could not contact anyone after the unit failed.

The P350’s gray cylindrical look is broadly liked, with reviewers calling it clean, modern, attractive, and easy to place visually. It avoids the bulky look some users disliked in other purifiers.

Design comments were generally favorable, with owners calling it attractive, good-looking, and suitable for bedrooms or living spaces.

Indicator-ring expectations are mixed because this model lacks the richer display features found on other Levoit units. The comments point more to missing readouts than poor readability.

Reviewers liked the clear digital readout, clean-air percentage, and easy-to-understand display.

Setup documentation is mostly seen as clear enough, with customers saying instructions were easy to understand. The main caution is that the internal filter plastic can still be missed during setup.

Documentation was mixed: one owner praised the manual access, while another said troubleshooting directions did not resolve the failure.

Durability comments are positive but sparse, including one short customer review that grouped durability with ease of use and fit. Longer-term reliability is better represented under reliability.

Durability was a major concern, with many customers reporting failures within weeks, months, or about a year.

Dust control is one of the strongest customer themes, with many owners reporting less surface dust, cleaner filters, and even cleaner HVAC filters. One negative review said it seemed to push dust and hair around instead of filtering it.

Dust removal was usually praised by pet owners and dusty-home reviewers, though one apartment reviewer found it weak unless run constantly.

Owners find the purifier easy to set up, operate, clean, and live with. The simple buttons and quick unboxing process come up repeatedly in positive reviews.

Set-up and daily operation were widely described as easy, with several users praising set-and-forget operation.

Expert testing describes the P350 as energy efficient for its class, especially compared with the Core 300. Power use is not a major customer complaint.

The three manual speeds plus sleep mode give users enough control for everyday use. Reviewers like using higher speeds for quick cleaning and lower speeds for quieter background operation.

Fan-speed control was useful, but higher speeds and speed changes could bring noticeable noise.

Replacement filter availability is a plus for some buyers, especially because filters are easy to find on Amazon and arrive quickly. Availability was not a repeated problem.

Filter availability was mixed: one customer found filters readily available, while another could not find Shark-brand replacements.

Filter life is mixed: many users get about six months, but dusty or pet-heavy homes may need earlier changes. One reviewer said their filter did not make it a month, while another got years from HEPA filters with added carbon foam.

Filter life evidence was mixed, ranging from long-lasting filters to complaints that the filter dropped quickly or lasted only two months.

Filter cost is the most common ownership-cost complaint. Some owners call filters pricey or say to budget for replacements, though others find them affordable or worth the odor reduction.

Filter cost drew repeated complaints, though a few buyers found filters reasonable or saw savings from cleanable parts.

Experts describe a competent three-stage system built around a pre-filter, particle/HEPA stage, and carbon layer. The filtration stack is treated as the core reason the unit works well for pets.

Handle design is a real drawback for people who move the unit often. Several comments say it is awkward to carry because there is no handle or grip.

HEPA filtration is generally treated as a strength, especially for pet allergens and fine particles. One customer felt the included filter was not enough and recommended upgraded HEPA filters.

HEPA filtration was cited positively by reviewers who connected it with solid cleaning performance.

Indicator and display features are useful but imperfect. Users like being able to turn off lights at night, while others complain the filter reminder acts more like a timer than a true condition sensor.

The color light indicator was liked because it made air quality status easy to understand.

Most owners do not report chemical or strange smells, and a few specifically praise the lack of odor from the unit. A small number had the opposite experience, including a foul smell after a few months.

Reviewers who mention ionization treat its absence as a plus, especially around pets and ozone concerns. Experts also describe the filtration system as ozone-free without ionizer or UV-C stages.

Listing accuracy is a mixed spot. Some customers say the purifier matched the description, while others were frustrated by missing placement guidance or felt the pet version was too similar to cheaper Core 300 models.

Maintenance is generally considered simple: wipe the grilles, vacuum the filter exterior, and replace filters when needed. Several customers describe filter cleaning or replacement as easy.

Filter changes and basic upkeep were often easy, but reset problems and sensor cleaning complaints were recurring negatives.

Noise feedback is mostly positive at low and sleep settings, often described as quiet white noise. Complaints cluster around higher speeds, squeaks, or aging units that became louder over time.

Most reviewers found low or auto settings quiet, while high speed, cycling, or failing auto mode could become loud or annoying.

Odor reduction is the standout strength, especially for litter boxes, dog smell, musty rooms, cooking odors, smoke drift, and RV smells. Many customers describe a dramatic before-and-after change.

Odor reduction was often strong for cooking, smoke, pets, and skunk smell, but several pet-odor and apartment reviews were disappointed.

Overall satisfaction is very high, with many customers buying additional units or saying they love the purifier. The few unhappy owners cite noise, weak allergy results, or poor value after a defect.

Overall satisfaction leaned positive, with many repeat purchases and recommendations, offset by strong dissatisfaction from failed units.

Ozone-free operation is viewed positively by pet owners and headache-sensitive users. Reviewers liked that it avoids ozone or ionizer features while still improving air quality.

Particle removal performs well in expert testing and customer filter checks. Reviews mention 94% particulate reduction, dirty used filters, and visible debris captured over time.

One review praised broad sensing across dust, allergens, dander, and smoke.

Pet dander and fur reduction are major reasons people buy this model, and most pet owners report cleaner air, fewer symptoms, and less visible hair or dander. One negative review said it pushed dog hair and dust around.

Pet owners commonly credited the unit with helping dander, pet hair, and pet-related air quality.

PM2.5 results are strong in expert testing, with one review measuring a 94% PM2.5 improvement. The limitation is that the purifier itself does not provide PM2.5 readouts.

Pollen comments are fewer than pet and dust comments, but they are positive. Customers mention relief on pollen days and less pollen settling in a nursery.

Portability is mostly good because the unit is compact and light enough to move between rooms. The lack of a handle keeps it from being effortless for everyone.

Owners liked being able to move the unit between rooms and described it as lightweight.

Experts measured modest power draw and described the unit as inexpensive to run. It is built for long operating hours without major energy complaints.

The pre-filter gets positive marks for catching larger contaminants such as dust, hair, fur, and dander. Experts describe it as improved, though it still needs regular vacuuming.

Real-time monitoring is absent, and reviewers clearly miss it. Buyers wanting live air-quality readings or automatic response should choose a smarter model.

The live clean-air percentage and visible air-quality feedback were repeatedly praised when the sensor worked.

Reliability is mostly favorable, with several owners reporting years of trouble-free use. The negative side includes a foul odor within three months and an older unit developing bearing-like noise.

Reliability was polarized: some units worked for a year or more, while many others developed sensor or power failures.

Remote control is not included, and one expert said the purifier would be more convenient with it. The lack of remote control reinforces the basic-controls tradeoff.

Filter replacement is easy once the user understands the bottom-access design, but setup mistakes are possible if the filter remains wrapped or is inserted incorrectly. Customers praised easy swaps after the initial learning curve.

Replacement evidence was mixed, with some easy warranty or company replacements and others frustrated by returns or unresolved requests.

Room coverage works best in bedrooms, offices, nurseries, and other small to medium spaces. Negative comments usually come from using it beyond its intended square footage.

Many owners felt it handled large rooms, multiple rooms, or separate levels, while a few found real-world coverage weaker than claimed.

A couple of users noticed a cooling or air-mixing effect from the upward airflow. This is a side benefit rather than a dedicated temperature feature.

Timer controls are appreciated, but scheduling is limited. Users who want automatic daily on/off schedules or app-based routines see this as a clear miss.

The size is a major selling point for bedrooms and smaller rooms, with many owners calling it compact, nightstand-friendly, and easy to place. It is not tiny, and larger rooms need a bigger model.

The unit was sometimes praised as compact or space-saving, though one customer found it larger than expected.

Sleep mode is praised for quiet nighttime operation and dimmer lights. Several owners use it in bedrooms or move the unit there for sleep.

Sleep mode was praised for dimming lights and making bedroom use easier.

Sleep benefits are a repeated customer theme, mostly from cleaner breathing and gentle white noise. Several owners said they woke with less congestion or slept noticeably better.

Smart features are minimal, and experts repeatedly call that out. There is no app, Wi-Fi, auto mode, or real-time air-quality feedback.

Smart-feature evidence was positive for useful controls and display features but negative where customers wanted remote control or lost sensor/filter-life functions.

Smoke removal is supported by expert testing and a few customer experiences with wildfire or smoke drift. Cigarette smoke expectations should stay realistic, especially in active smoking spaces.

Smoke removal was a repeated strength in cooking, cigarette, neighbor-smoke, and wildfire-smoke scenarios, though one wildfire review was disappointed.

True HEPA messaging is mixed. One expert says Levoit no longer claims True HEPA on newer materials, while another still describes the filter as True HEPA and effective.

Value is mostly praised because the P350 delivers strong pet-odor and small-room performance at a reasonable price. The value case weakens for buyers comparing it with cheaper Core 300 options or paying frequent filter costs.

Value was sharply split: happy owners called it worth the price, while failure, filter cost, or disappointing odor control made others call it overpriced.

Virus confidence is limited. One customer bought it with virus concerns in mind, while another wished it handled smaller virus-sized particles better.

VOC and gas reduction appears mainly through expert discussion of the carbon layer and one customer’s perfume/asthma experience. It is promising for smells and gases but not heavily tested by customers.

Warranty coverage is basic but can improve with registration. Reviewers mention the one-year warranty and a second year available after registering.

Washability is a minor frustration, with one customer wishing the filters could be washable. No review presents a washable pre-filter as a product strength.

One customer valued being able to clean part of the filter with a rag and avoid frequent filter buying.
