LEVOIT Core 100S VS LEVOIT Core 300S
If you are shopping for a smart air purifier, the LEVOIT Vital 100S P and LEVOIT Core 300S P are two of the most popular options because they promise the same big benefits: cleaner air, quiet operation, and app based control that lets you set it and forget it. Both are designed to help with everyday indoor air issues like dust, pollen, smoke particles, and pet dander, and both connect to the VeSync app for schedules, Auto Mode, and voice control through Alexa or Google Assistant.
In this comparison, we are going to break down what actually matters for real life use, not just spec sheet numbers. We will compare room coverage, air cleaning power, and noise levels for sleep, then look at practical differences like pet focused features, smart automation, filter setup, and overall day to day convenience. By the end, you will know which model makes more sense for your space and your priorities, whether you want the more pet friendly design of the Vital 100S P or the compact, energy friendly, all around approach of the Core 300S P.
Key Takeaways
- The Vital 100S-P is the better choice if you have pets, because it is designed to pull in more pet hair and dander, while the Core 300S-P is the cleaner all around pick if you just want a simple smart purifier for everyday use.
- They clean air at almost the same pace, with the Vital at 143 and the Core at 141 on their airflow rating, so most people will not notice a big difference in speed.
- Both are meant for bedrooms and living spaces, and their “room size” numbers are nearly identical, so your decision is more about features than coverage.
- If you are sensitive to sound at night, the Core is a touch quieter on paper, but both can run quietly on their lowest settings.
Both work with the VeSync app and Alexa or Google voice control, but the Core uses less power overall, which can matter if you run it all day.

Factors to Consider When Choosing LEVOIT Air Purifiers for 2026
Start with what you are trying to fix, because the “best” air purifier depends on your air problem. If your home deals with pet hair and dander, you will care more about pre filter design and how easy it is to keep clean. If your issue is seasonal allergies, you will care more about overall airflow and consistent run time. If you cook a lot or have lingering smells, activated carbon matters more than most people realize. The right choice is the one that matches your space and your habits, not the one with the biggest number on a listing.
Next, pay attention to how you will actually use it day to day. In 2026, a lot of buyers want a purifier that can run in the background without constant adjustments, which is where Auto Mode and app control become genuinely useful. You are not just buying a machine, you are buying a routine, and the models that fit into your routine are the ones you keep running.
Room Size and Airflow
Room size claims can be confusing, so focus on two ideas: light cleaning for a big space versus faster cleaning for a smaller space. Many air purifiers can “cover” a large room if you are fine with a slower refresh, but they feel most effective in bedrooms, offices, nurseries, and medium living spaces where you want the air cleaned multiple times per hour.
A simple way to think about it is this: if you want noticeable results, size up for the room you are using most, not the entire house. If you spend most of your time in one bedroom and a family room, you will usually get more value from placing the purifier where you sleep and where you relax, instead of expecting one unit to do everything.
Filtration and Filter Costs
Most modern air purifiers use a layered approach: a pre filter for larger particles, a main filter for fine particles, and activated carbon for odors and cooking smells. What matters for you is not just that those layers exist, but how often you will need to replace them and how annoying it is to maintain them.
A washable pre filter can be a big deal because it takes the daily mess off the main filter, especially if you have pets, kids, or a dusty home. Filter replacement is the long term cost of ownership, so in 2026 it is smart to check two things before buying: how easy it is to find the replacement filter, and whether the filter change schedule fits how often you plan to run the purifier.
Noise, Smart Features, and Energy Use
If an air purifier is too loud, you will stop using it, so noise matters more than most shoppers expect. Look for a model that stays comfortable on low at night and can ramp up automatically when the air gets worse. The best experience is when you do not have to think about it, it just adjusts in the background.
Smart features are not just a gimmick when they save you time. App schedules, Auto Mode, and voice control help you run the purifier more consistently, which is what actually improves results. Energy use also matters if you run it all day, so if two models perform similarly, the one that uses less power can be the smarter long term choice.
FAQ: What Do You Need to Know About Air Purifiers
Do air purifiers help with allergies?
They can help by reducing airborne particles like pollen, dust, and pet dander, but they work best when you also control the source, like frequent cleaning and keeping windows closed on high pollen days.
How do I choose the right size air purifier for my room?
Match the purifier to the room where you will use it most and aim for faster cleaning in that space rather than slower cleaning across a whole floor.
What is CADR and why should I care?
CADR is a standardized airflow performance rating, and a higher number usually means the purifier can clean the air faster in a given room.
Should I run an air purifier all day or only when needed?
Running it consistently is usually more effective, especially on a lower setting, because particles build up continuously from normal living.
Where should I place an air purifier in a room?
Put it where airflow is not blocked, a few feet away from walls and furniture, and closer to the area where you spend the most time.
Do air purifiers remove odors?
They can reduce odors, but results depend heavily on the amount and quality of activated carbon and how strong the odor source is.
Do air purifiers remove smoke from cooking or wildfires?
They can reduce smoke particles, but for heavy smoke events you usually need higher airflow, good sealing, and consistent run time to keep up.
How often do I need to change the filter?
It depends on usage and air quality, but most people replace main filters every few months, sooner if they run the unit hard or have pets.
Can an air purifier prevent getting sick from viruses?
An air purifier can reduce airborne particles, but it is not a substitute for ventilation, vaccination, or medical guidance, and it should be treated as one layer of protection.
Do I need one air purifier per room?
If you want strong results in multiple rooms at the same time, yes, because air cleaning is most effective when the unit is sized and placed for that specific room.
