The Medify MA-25 is a compact air purifier that can purify up to 500 square feet of rooms. Its unique air flow system with dual side air intakes and a front air outlet ensures efficient and effective air cleaning. 

The 3-stage air cleaning system consisting of a pre-filter, a True HEPA filter, and an activated carbon filter captures large particles, allergens, virus particles, pollen, mold, fungi particles, and toxic odors and formaldehyde. 

The tempered glass control panels add a premium look to the air purifier, which is available in both black and white color options.

The MA-25’s ACH rating of 1X to 4X means that it can cover a space of 250 to 1000 square feet depending on the number of air exchanges per hour. 

However, Medify Air recommends using the MA-25 in smaller spaces based on its CADR rating. 

In our testing, the air purifier was able to clean up to 500 square feet area with 99.9% efficiency for trapping particles down to 0.3 microns, making it a suitable choice for bedrooms, living rooms, and small offices.

One of the standout features of the MA-25 is its affordability in the low-range air purifier market, making it an excellent value for loyal users. It is also smaller in size than the MA-40 model, making it easier to place on tabletops or nightstands.

However, the design of the Medify MA-25 is not particularly distinctive and is similar to other Korean air purifiers. The rectangular shape of the body and the tempered glass control panels are typical of Korean air purifier models from Samsung, Coway, and Winix. While the design is not unique, it is still sleek and modern.

In terms of performance, the Medify MA-25 outperformed similarly priced air purifiers such as the Oreck Air Response Medium. However, some users may miss the ionizer feature that has been removed from the latest devices of many air purifier companies, including Medify Air.

Overall, the Medify MA-25 is an excellent air purifier for filtering 500 sq ft, and its benefits include affordability, efficient air cleaning, and a compact size suitable for smaller spaces.

The air purifier also has a 360-degree air input and a bottom-to-top airflow system that maximizes dual air filtration.

The Winix XLC has a sleek, yet simple design that may not be as stylish as some other air purifiers in its class, but it is practical and functional.

The Winix XLC is AHAM verified and can clean the air in any room with full confidence. It has a great CADR rating that can challenge other brands, with CADR ratings of 355 Dust/ 400 Smoke/ 400 Pollen (cfm). The air purifier is powerful enough to clean an AHAM-verified room size every 15 minutes.

The Bissell air320’s performance is better than the TruSens Z-2000, but it is lower than the Oreck Air Response Large, Vornado AC550, and Vornado PCO300.

In terms of drawbacks, the Bissell air320 has a higher noise level than the library mode, but it still offers enough options to keep the noise down. The white color of the Bissell air320 is not as solid as the Bissell air220’s black color. 

However, this is merely a cosmetic issue and does not affect the air purifier’s performance in any way.

In conclusion, the Bissell air320 air purifier is the best option for filtering 500 square feet of rooms.

How Do I Choose An Air Purifier For 500 Square Feet?

With so many different models available, it can be challenging to determine which one is right for your needs. In this article, we will guide you through the process of selecting an air purifier for a space of 500 square feet.

Determine The Type Of Air Purifier You Need

There are several types of air purifiers available, each with their own specific function. The three most common types are HEPA, activated carbon, and ionizer purifiers.

HEPA (High-Efficiency Particulate Air) filters are the most popular type of air purifier. They work by removing airborne particles such as pollen, dust, and pet dander. HEPA filters are very effective at capturing particles that are 0.3 microns in size or larger.

Activated carbon filters are used to remove odors and harmful gases. These filters are effective at removing cigarette smoke, cooking odors, and volatile organic compounds (VOCs).

Ionizer purifiers work by releasing negative ions into the air. These ions attach to airborne particles and make them heavier, causing them to fall to the ground.

For a space of 500 square feet, a HEPA air purifier is likely the best option.

Consider The Cadr Rating

CADR (Clean Air Delivery Rate) measures an air purifier’s ability to remove pollutants from the air. It is important to choose an air purifier with a CADR rating that matches the size of your room. A CADR rating of at least 300 is recommended for a space of 500 square feet.

Determine The Air Changes Per Hour

The air changes per hour (ACH) is a measure of how many times an air purifier can filter the air in a room in an hour. The higher the ACH, the more times the air in your room will be filtered.

For a space of 500 square feet, a minimum of 2 ACH is recommended. However, a higher ACH is better, especially if you have pets or suffer from allergies.

Look For Additional Features

Some air purifiers come with additional features that can be useful. For example, some models have a timer function that allows you to set the air purifier to turn on or off at specific times. Others have a sleep mode that reduces noise levels while still filtering the air.

Consider The Noise Level

The noise level of an air purifier is an important factor to consider, especially if you plan to use it in a bedroom or other quiet space. Look for models that have a noise level of 40 decibels or less.

Determine The Cost

The cost of an air purifier can vary greatly, depending on the features it offers. However, it is important to choose a model that fits within your budget. Air purifiers for a space of 500 square feet typically cost between $100 and $300.
