However, the AllerAir AirMedic Pro 6 is also one of the heaviest air purifiers in the world, weighing in at 58 lbs. It is also slightly bigger than other high-end air purifiers like Austin Air and Airpura, which may be a consideration for those with limited space. 

Additionally, the air purifier is more expensive than some other models on the market, which may be a drawback for budget-conscious consumers.

What sets the AllerAir AirMedic Pro 6 apart from its competitors is its powerful 4-stage air cleaning process and customizable Activated Carbon filter.

Additionally, the T600 DLX’s enhanced carbon filter can be upgraded to use potassium permanganate to accelerate binding of light gases, making it one of the best in the world.

Overall, we believe that the AIRPURA T600 air purifier and humidifier is an excellent choice for those looking for an air filtration system for their homes or offices. 

Its ability to filter out harmful contaminants, particularly cigarette smoke and cigar odors, is impressive, and its eco-friendly design makes it an excellent choice for those looking for an environmentally friendly option. 

Its compact size, easy mobility, and efficient filtration system make it an ideal choice for grow rooms. While it may not be as luxurious as some of its competitors, its effectiveness and affordability make it an excellent choice for most users.

How Do I Keep The Air Clean In My Grow Room?

Growing plants indoors in a confined space, such as a grow room, can lead to poor air quality due to the presence of contaminants, odors, and moisture. To ensure healthy plant growth and maintain a comfortable environment for humans, it is essential to keep the air clean in a grow room. Here are some tips on how to achieve this:

Use an air filtration system: An air filtration system is one of the best ways to keep the air clean in a grow room. Choose an air purifier with multiple filters, including a HEPA filter to remove airborne contaminants and an activated carbon filter to absorb odors.

Control humidity: High humidity levels in a grow room can lead to the growth of mold and mildew, which can negatively impact air quality. Use a dehumidifier or an air conditioner to keep humidity levels below 60%.

Proper ventilation: Proper ventilation is crucial to maintaining clean air in a grow room. Ensure that your grow room has an adequate ventilation system in place. An exhaust fan can remove stale air and bring in fresh air.

Avoid chemical fertilizers and pesticides: Chemical fertilizers and pesticides can release harmful chemicals into the air, impacting both plant health and air quality. Instead, opt for organic alternatives.

Keep the grow room clean: Keeping the grow room clean is vital to maintaining good air quality. Regularly clean surfaces and floors with natural cleaning products, and remove any dead plant matter promptly.

Now that we have covered how to keep the air clean in a grow room, let’s discuss how to get fresh air into a grow room.

One of the simplest ways to get fresh air into a grow room is to open a window or door. However, this method can be risky, as it can also let in unwanted pests and contaminants.

A better way to get fresh air into a grow room is by using a dedicated intake fan. This fan can draw in fresh air from outside and distribute it evenly throughout the room. It is essential to install a carbon filter on the intake fan to remove any contaminants from the incoming air.

Another option is to use a duct system to bring fresh air into the grow room. This method is ideal for larger grow rooms, as it can distribute fresh air evenly throughout the space.

How Do I Control The Smell In My Grow Room?

We’ll discuss some methods for controlling the smell in your grow room, including the use of a carbon filter.

Method 1: Ventilation

One of the easiest ways to control the smell in your grow room is through proper ventilation. This involves circulating fresh air into the grow room and venting the stale air out. 

A good ventilation system will help to dilute the odor in the air and maintain proper humidity levels. It’s important to note that proper ventilation doesn’t mean leaving windows open or using a fan. An exhaust fan and a carbon filter should be used to keep the air clean and odor-free.

Method 2: Odor Neutralizers

Another option for controlling the smell in your grow room is the use of odor neutralizers. These products work by breaking down the compounds in the air that cause the smell. 

There are a variety of odor neutralizers available on the market, including sprays and plug-in devices. While these products can be effective in reducing the smell, they don’t eliminate it completely.

Method 3: Carbon Filters

Carbon filters are one of the most effective ways to control the smell in your grow room. These filters work by pulling air through a layer of activated carbon, which absorbs the odor-causing compounds. 

Carbon filters are a popular choice for growers because they not only eliminate the smell but also improve air quality by removing harmful toxins and chemicals from the air. A high-quality carbon filter can last for several years, depending on usage.

So, do you need a carbon filter in your grow room? The answer is yes, if you want to control the smell and maintain a healthy environment for both you and your plants. 

While ventilation and odor neutralizers can be effective, they don’t provide the same level of odor control as a carbon filter. Investing in a high-quality carbon filter will not only help to control the smell but also improve the overall air quality in your grow room.

The AllerAir AirMedic Pro 6 Pro boasts a powerful 4-stage air cleaning process, while the Coway Airmega 400S offers an all-in-one filter that captures up to 99.97% of airborne particles. 

The HATHASPACE HSP003 provides a dual filtration system that effectively targets various pollutants, including PM2.5 particles. 

All three options have features specifically designed for grow room use, such as the highly effective Activated Carbon filter of the AllerAir AirMedic Pro 6 Pro, the Max2 filter of the Coway Airmega 400S, which reduces more than 99% of volatile organic compounds and fumes, and the honeycomb activated-carbon filter of the HATHASPACE HSP003, which absorbs odors, smoke, and VOCs. 

Ultimately, choosing the best air purifier for your grow room will depend on your specific needs and preferences.
