Core Differences at a Glance: MA5K vs MA5000

At first glance, the MA5K and MA5000 appear similar. However, their internal design, durability, and long-term value differ in ways that directly impact performance over time.

What These Differences Mean in Real Use
The most important distinction is the ozone plate design. With the MA5K’s integrated plate, ozone output slowly decreases as the unit ages. In contrast, the MA5000 allows you to restore peak performance simply by replacing the plate—making it a better choice for frequent or long-term use.
The MA5000’s heavier build isn’t about portability—it adds stability during extended purification cycles, which is especially useful for commercial spaces or persistent odor problems such as smoke, pet urine, or mold.
How to Use MA5K & MA5000 Safely and Effectively
Both models follow the same safety-first operating principle: ozone treatment should only be used in unoccupied spaces. When used correctly, ozone is a powerful and widely adopted method for eliminating stubborn odors in homes, vehicles, and commercial environments.

General Operating Steps (Both Models)
-
Prepare the Space
Remove visible odor sources such as trash, pet waste, or smoke residue. Close all windows and doors, and ensure no people, pets, or plants remain inside the area. -
Set the Timer
Adjust the dial according to odor intensity. For difficult cases, the MA5000’s “HOLD” mode allows continuous output.
Recommended Run Times (Up to 2,000 sq ft):- Mild odors (cooking smells, fresh paint): 30–60 minutes
- Moderate odors (pet smells, cigarette smoke): 60–90 minutes
- Severe odors (mold, water damage): 90 minutes–2 hours (MA5000 recommended)
-
Exit and Secure the Area
Leave immediately after starting the unit. Place the included “No Entry” warning sign to prevent accidental exposure. -
Ventilate Thoroughly
After the cycle ends, wait about 30 minutes for ozone to naturally convert back into oxygen. Then ventilate the space for 5–10 minutes before re-entering.

Model-Specific Notes
-
MA5K:
Its lightweight design makes it easy to move between bedrooms, apartments, or vehicles. No maintenance is required—once performance declines, the unit has reached the end of its service life. -
MA5000:
Built for stability during longer sessions. Replace the ozone plate approximately every 5,000 hours (about one year of regular use) to maintain strong output. Always unplug the unit before replacing parts.
Important Safety Notes:
Not available for use in California due to local regulations. Designed exclusively for air purification—do not use for food or utensil disinfection. Compatible with 110V power sources only.
Which One Should You Buy? A Practical Buying Guide

The right choice depends less on room size and more on how often you plan to use the unit.

Why it works:
The MA5K delivers reliable performance for light-duty needs while remaining easy to transport and budget-friendly.
Choose the MA5000 If You Need Frequent, Long-Term Performance

Final Verdict: Match the Machine to Your Usage Habits
Both the MA5K and MA5000 provide dependable ozone purification for spaces up to 2,000 square feet. The key difference lies in how often you’ll use the unit and how severe your odor challenges are.
- Choose MA5K for lightweight, occasional odor removal at a lower cost.
- Choose MA5000 for frequent use, tougher odors, and long-term value through replaceable components.
