Medify MA-25 Vs Levoit Core 300 – Side-by-side Comparison!

In this article, I will compare the Levoit Core 300 and the Medify MA-25. At first glance, they appear to be very different air purifiers, but in reality, they have more in common than you might think.

Almost identical features, 3-stage filtration, and nearly the same room coverage are just some of the specifications these two devices share. Levoit covers rooms up to 219 sq. ft. (20 m²), while Medify covers rooms up to 171 sq. ft. (16 m²).

Their huge popularity and strong market presence are qualities worth highlighting. The Core 300 is one of Levoit’s best-selling air purifiers, while the MA-25 is equally popular and highly sought-after in the Medify lineup.

Below, I will compare the Levoit Core 300 and Medify MA-25 features, performance, noise levels, and operating costs, and determine which is the better buy.

Specs: Medify MA-25 Vs Core 300

Performance Test – Comparison

Frankly, the performance tests were what I found most interesting in this comparison, mainly because these two air purifiers cover rooms of almost identical dimensions.

The Levoit Core 300 covers rooms up to 219 sq. ft. (20 m²), while the Medify MA-25 covers slightly smaller rooms, up to 171 sq. ft. (16 m²). Given the similar room coverage, I tested both devices under nearly the same conditions.

In the first test, performed in a 194 sq. ft. (18 m²) room, the Levoit Core 300 improved air quality by 93%, while the Medify MA-25 improved it by 94%.

Interestingly, in a room larger than the recommended size for both devices, the Levoit performed slightly better. In a 320 sq. ft. (30 m²) room, it improved air quality by 92%, compared to 91% for the Medify MA-25.

While the airborne particle removal results were similar overall, the Levoit Core 300 showed slightly better performance when it came to neutralizing odors.

Smoke Box Test – Comparison

I placed both air purifiers in a glass box, filled it with smoke, and measured how long each one took to clear it completely.

The Levoit Core 300 cleared the smoke in just 20 seconds, while the Medify MA-25 was slightly slower at 31 seconds.

As mentioned, the Levoit Core 300 edges ahead in both odor and smoke removal, likely due to its more effective carbon filter.

Noise Level Test – Comparison

When testing noise levels, the first thing I look at is the number of fan speeds. The Levoit Core 300 has four, while the Medify MA-25 has three.

The Core 300’s slight advantage here comes from its four fan speeds and dedicated sleep mode, on which it is almost silent. It produces 40.7 dBA on sleep mode, compared to 41.8 dBA for the Medify MA-25 at its lowest speed.

At maximum speed, the situation is somewhat reversed. The Medify produces 64.0 dBA, while the Levoit is slightly louder at 64.9 dBA.

Overall, neither device is particularly loud, but I give the slight edge to the Levoit in this category, mainly because of its sleep mode, which is especially useful in a bedroom setting.

Operating Costs – Comparison

When determining which air purifier is more affordable to maintain, I always consider the cost of replacement filters and power use.

In terms of power usage, the Medify MA-25 runs on a 28W motor, while the Levoit Core 300 uses a 45W motor.

This means that running either device at maximum speed, 24 hours a day for a full month, would add approximately $2.31 to your electricity bill for the Medify, and about $3.81 for the Levoit.

When it comes to replacement filters, however, Levoit has a clear advantage over Medify, as it uses a longer-lasting filter that is also significantly cheaper.

Overall, the Levoit Core 300 is the more affordable option to maintain annually.

Features Overview

When talking about features, I must say that advanced options such as air quality sensor, auto mode, and the like you will not find with these two air purifiers.

Medify and Levoit have only basic features, which are quite enough for comfortable everyday use.

Filter Reset Indicator

A filter reset indicator is an option specific to both devices. It is basically an indicator located on the control panel that will light up when it is time to replace the old filter/s.

This is a beneficial feature because you will not have to track when it is time to replace the filter. 

Please keep in mind that filters on the Levoit Core 300 last between 6-8 months, while filters on the Medify MA-25 last about 3-4 months on average.

Timer

Another handy option common to both devices is the timer, which works by setting the time you want the device to turn itself off.

On Levoit, the timer can be set to 2h, 4h, 6h, or 8h, while on Medify the timer can be set to 1h, 2h, 4h, or 8h.

All in all, this is a very useful option, especially in the absence of advanced smart options that would provide a more advanced version of the timer.

Sleep Mode

Sleep mode is an option available only on the Levoit Core 300 model, and it is, in fact, the only option that distinguishes these two devices.

Basically, switching the device to sleep mode will dim all the indicators and switch the fan speed to the lowest.

Display Lock and Display Off

These two options are common to Medify and Levoit but are differently named.

Display Lock is used to lock the touch buttons and prevent accidental or unauthorized switching settings.

Display Off has a different purpose and serves to dim all the indicators on the device. On Medify, this option is a bit more advanced, as it offers several different brightness levels.

Airflow

What makes these two air purifiers even more different is the airflow. 

Levoit is cylindrical, and it has openings for air intake located at the bottom part. Medify MA-25 is rectangular. It has openings for air intake located on the sides. 

The filtered air comes out through the openings on top in the case of the Levoit Core 300, while on Medify it exits through the slots on the front.

Warranty

Before buying any product, it is always important to pay attention to all the features and the warranty that the manufacturer gives to the product.

Medify is far ahead of Levoit in this case, as it gives a lifetime warranty, but only if you subscribe to regular replacement filters through the Medify website.

Levoit, on the other hand, provides a 2-year warranty for the Core 300. However, I would advise everyone to register the air purifier on the Levoit website immediately after purchase to confirm the warranty.

Filtration Technology

When we talk about filtration, the biggest difference is that Medify has a dual filter placed on the sides. The filters on Medify are rectangular, while the filter on Levoit is cylindrical and hollow through the middle.

Both devices use 3-stage filtration technology, consisting of nylon mesh pre-filters, a True HEPA filter, and an activated carbon filter.

I am especially pleased that both devices use a True HEPA filter, especially since it is the primary filtration stage. Additionally, the True HEPA is the most responsible for the outstanding performance these two air purifiers have made.

Also, I am delighted with the quality of the carbon filter, especially since both devices have a pellet-based carbon filter.

Overall, Levoit and Medify use high-quality and highly efficient filters.

How to Replace Filters?

Since Medify and Levoit do not use washable filters, you should change the filters on these two devices from time to time.

Levoit Core 300 filter lasts on average between 6-8 months, while Medify MA-25 filters last between 3-4 months. Note that you do not have to manually track when it is time to replace the filter, as both devices use a filter reset indicator that will notify you when old filters need to be changed.

The process of replacing the filter is straightforward, and I explained it in detail in the individual reviews that you can find at the links below.
