Commercial Grow Room Air Purification & HVAC Sanitization Systems

High Airflow. Real Filtration. Proven Pathogen Control.

Stop mold, mildew, and airborne contamination at the source with air systems built specifically for indoor cultivation.

🌬 The Problem Most Growers Miss

Indoor cultivation doesn’t just grow plants — it creates a closed-loop contamination system.

Air continuously moves:

• Mold spores

• Powdery mildew

• Bacteria and yeast

• Dust and particulate matter

Through:

• HVAC systems

• Oscillating fans

• Worker movement

• Dense plant canopies

👉 If you’re not actively cleaning the air, you’re recycling contamination all day.

⚠️ Where the Industry Got It Wrong

Most “grow room air purifiers” are built backwards:

• Weak fans

• Low airflow (CFM)

• Heavy reliance on ionization

• Minimal real filtration

They try to “treat” dirty air instead of removing contaminants from circulation.

✅ The Mammoth Approach: Airflow First — Capture, Then Destroy

We prioritize what actually matters:

1. MOVE AIR — High CFM / High ACH

You can’t clean air that isn’t moving through the system.

2. CAPTURE CONTAMINANTS — HEPA

Physically capture mold spores, PM, pollen, and other particulates.

3. DESTROY WHAT’S LEFT — PCO + Plasma + UVC

Active technologies help neutralize remaining biological and chemical contaminants.

🔬 6-Stage Purification System

Prefilter – Stops large debris
HEPA Filter – Captures mold spores, PM, pollen, and particulates
Activated Carbon – Removes VOCs and odors
PCO (Photocatalytic Oxidation) – Breaks down contaminants using photocatalytic oxidation
Plasma Ionization – Helps deactivate airborne microbes
UVC – Final treatment stage

👉 This is not ionization-first. This is filtration-first.

🔎 What Is PCO (Photocatalytic Oxidation)?

PCO uses UV light and a TiO₂ catalyst to generate reactive species that can break down biological and chemical contaminants, including:

• Mold

• Bacteria

• Viruses

• VOCs

👉 Your first line of defense

📊 Airflow Is Everything — ACH Explained

Air Changes Per Hour (ACH) is the number of times the total volume of room air could theoretically pass through the purification system in one hour.

ACH = CFM × 60 ÷ Room Volume

For commercial cultivation, we recommend sizing systems based on the room, airflow, and desired ACH rather than simply counting units.  10-12 ACH should be the target

📐 Real Room Examples — Using 400 CFM

👉 Larger rooms may require multiple units or HVAC integration.

Use 400 CFM for the wall unit or 350 CFM for the medium size unit.  

🔧 Maintenance

Filter life depends heavily on room cleanliness, particulate load, and operating conditions.

Typical replacement intervals:

• HEPA filter: up to 5,000 hours

• Carbon filter: up to 2,500 hours

• UV lamp: up to 7,500 hours

Actual replacement intervals will vary based on operating conditions.

🧠 Why Mammoth Is Different

Most Competitors:

• Prioritize ionization over filtration

• Move too little air

• Use weaker airflow systems

• Don't adequately address room-wide air turnover

Mammoth Systems:

• High airflow with real CFM

• HEPA-first capture strategy

• True multi-stage purification

• Designed for dense commercial canopies

• Built around consistent air treatment — not just marketing specs

👉 We’re focused on moving contaminated air through the system, capturing what we can, and actively treating what remains.

🎯 What This Means for Your Grow

• Lower airborne microbial load

• Reduced particulate pressure

• Fewer opportunities for contamination to spread

• Cleaner growing environments

• More consistent crop quality and COAs

❓ Frequently Asked Questions

What is the best air purifier for a grow room?

Look for a system that combines sufficient airflow (CFM), HEPA filtration, and active technologies such as PCO and UVC.

Why does airflow matter?

If air isn’t moving through the purification system, contaminants aren't reaching the filters and treatment stages. Airflow determines how much room air the system can process.

What causes mold in grow rooms?

Mold pressure can increase with high humidity, stagnant air, and airborne spores circulating throughout the facility.

How do I help prevent powdery mildew?

Managing humidity, airflow, environmental conditions, and airborne contaminants can all help reduce the conditions that allow powdery mildew to spread.

What is ACH and why does it matter?

ACH is a way to measure room air turnover based on the system's airflow and room volume. Higher ACH means the purification system can process the room's air more frequently.

Is ionization alone enough?

Ionization is only one part of an air-treatment strategy. Combining particle capture with active treatment provides a more comprehensive approach.

Do Mammoth units produce ozone?

No. Mammoth commercial air sanitizers are designed for ozone-free operation.

Should I use HVAC purification too?

For larger commercial facilities, HVAC treatment can add another layer of protection by treating air as it moves between rooms and through ductwork.

How many units do I need?

It depends on room dimensions, ceiling height, airflow, and your target ACH. We can help size the system for your facility. 

Use 400 CFM for the large unit and 350 for the medium size unit

🔁 Simple Truth

If you’re not moving contaminated air through a purification system fast enough, you’re just recirculating it.

✅ The Mammoth Formula

High Airflow → HEPA Capture → PCO + Plasma + UVC Treatment → Cleaner Air → Better Growing Environment
