The air in large rooms can be difficult due to being spacious, so to help maintain fresh air, you will need the best air purifier for 1500 sq ft. We know how hard it is to maintain a large room, such as a family room, living room, guest room, master’s bedroom, kids’ room, and the like, so we wrote this guide.
Whether you have the best air purifier for the nursery, the kitchen, or any other room, the most important aspect to look for is whether or not it is rated for your room size. After all, if your air purifier is too small, it will not be enough to constantly filter the air and it may result in your motor and filter getting clogged.
Therefore, it’s important to select an air purifier that suits your room size needs. We have some suggested picks above that we think are ideal for large rooms around 1,500 square feet or more.
Which air purifier covers the most square footage?
So far, there are many choices for the best air purifier for 1500 sq ft out there. However, the LEVOIT Core 600S has great coverage of up to 3,175 square feet, making it one of the air purifiers in the market today with the largest room coverage.
When it comes to cleaning power, this air purifier has the following specs:
- H13 True HEPA (medical-grade)
- Wi-Fi and Alexa compatibility
- High CADR of 410 CFM (cleans fast)
We highly recommend this air purifier for those who just moved in and/or are still in the process of renovating their home or living/office space (great for filtering sawdust, paint odors, and the like). What’s more, it will also appeal to folks living in high-ceiling spaces due to its high cleaning capacity.
Another air purifier that we found has a high coverage is the Purafide XP360, which is good for rooms up to 2,200 square feet. it also has H13 HEPA and it even has a 6-stage filter system, making it suitable for very polluted homes or areas.
If you have an office space and want something sleek and stylish (different color choices are available), we think this is a great choice. It even has a humidity monitor and 5 fan speeds to choose from. Another plus point with this unit is that the H13 HEPA filter can last up to 2 years before replacement.
What is the most highly recommended air purifier?
A brand of air purifiers that’s trusted by most consumers and health experts is Medify. One of their units, the Medify MA-112 Air Purifier, can run smoothly and clean the air of a room up to 2,500 square feet within an hour.
Here’s what we like about this unit based on its specifications:
- It has a sleep mode that dims the lights and lowers the fan speed
- It comes with an 8-hour timer
- There’s also a child lock (great for kids’ rooms)
- It uses H13 True HEPA with an activated carbon filter for odors
If you want the best air purifier for a dorm room, the Coway Airmega 400(G) is a great unit to consider, which can cover up to 1,560 square feet. It also has both a true HEPA filter and activated carbon, making it suitable for smelly rooms.
For those who don’t want a very loud unit running in the middle of the night (or while reviewing for exams), its 43.2-dB noise level won’t be jarring to your ears. What’s more, it also has an air quality sensor that updates in real time.
Is it better to have one large air purifier or multiple small ones?
This dilemma largely depends on the type of room you want to clean. Is it well-ventilated? How are the windows placed? Can an air purifier cover every small nook in the room? It all depends on the air circulation of the area.
If your room has poor air circulation, adding up small yet powerful air purifiers can be sufficient. However, for large spaces that have just the right amount of ventilation, such as studio-type rooms, you’ll benefit more from a large air purifier.
How big of an air purifier do I need for my house?
It all depends on which rooms are greatly affected by pollution, the ventilation in those rooms, and the area of those rooms in square feet.
The CADR or Clean Air Delivery Rate is an important factor when choosing an air purifier for your room size. You’ll need the total volume of your room (e.g., 15 x 15 x 8 ft. = 1,800 cu. ft.) and identify the CADR of the air purifier.
Supposed you have 410 CFM (LEVOIT Core 600S). Multiply 410 by 60 to get 24,600 cubic feet per hour and then divide it by the cubic feet (24,600 / 1,800 = 13.67 ACH or air changes per hour). An ACH of at least 5 per hour is recommended for allergy sufferers, and this is more than enough!
What is the CADR of an air purifier?
The CADR or clean air delivery rate is the efficiency of an air purifier to remove pollutants from your indoor space. Most air purifiers have at least 100 to 300 CFM for their CADR. A higher CADR means that your air purifier will clean faster.
Are large air purifiers loud?
Not all of them – most air purifiers we suggested here have a low noise level. For instance, the Medify MA-112 can only reach up to 43.2 dB on its noise level (it even has a sleep mode) to help you sleep peacefully at night (or study/focus during the day).
What air purifier should I buy if I have a high ceiling?
If you will buy an air purifier for large areas, you need to consider both the area of the room and the ceiling height. A higher ceiling will be more difficult to clean for an air purifier so you might need a unit that exceeds the intended square feet (or use our formula for ACH above).
So, what is the best air purifier for 1500 sq ft? We think it’s the LEVOIT Core 600S since it’s suitable even for much bigger spaces and it has a high ACH compared to most units. This makes it suitable for spaces near polluted cities, factories, and the like since it can clean air faster than most air purifiers out there.
