How Safe Is Reme Halo?

By Aztil –

As a professional AC service company, we constantly get asked to provide our opinion on the Reme Halo. Usually, the popularity of a device is enough to dispel rumors, but in this case, there are many people unfamiliar with Reme Halo warning about its dangers.

Why is this the case and do these rumors have any basis in reality?

Spoiler alert: the concerns are wildly exaggerated. But there are still grains of truth in the claims and it all boils down to a single molecule – ozone.

Today, we’ll explain how Reme Halo works and outline cases in which the ‘’dangerous’’ Reme Halo warning applies.

Reme Halo – How It Works

For the uninitiated, the way Reme Halo works can seem like science fiction, but it’s simple really. This air purifier uses ionized hydrogen peroxide to purify the air in your air duct system. This is all made possible through photohydroionization which converts moisture from the air into hydrogen peroxide.

This process was developed by the company behind Reme Halo and its main purpose is to simulate the hydroperoxides which naturally occur in the air outside. 

In simple turns the following elements in this device work in conjunction to create ionized hydrogen peroxide:

1. A catalytic surface made of rhodium, copper, titanium dioxide, and silver

2. Moisture that flows through your HVAC system

3. A source of light that interacts with the moisture that collects on the catalytic surface

These ionized hydrogen peroxide particles are then released into the atmosphere through your air ducts. 

Since these molecules are ionized, they attract all kinds of negative particles such as mold, viruses, dust, pollen, bacteria, etc. This neutralizes the negative particles while at the same time, it also makes them larger. This makes your air filter more effective as it has an easier time trapping harmful fragments.

Along with this, the Reme Halo also uses bipolar ionization to positively or negatively charge air molecules. When these particles collide with microbes they trap them and remove hydrogen from their cell walls – making them harmless in the process.

Is Hydrogen Peroxide Safe?

While this ‘’chemical’’ sounds like the suspect part of the Reme Halo warning, it’s actually not. Hydrogen peroxide produced by this air purifier is perfectly safe and there are even fewer particles produced than occur outdoors naturally.

Additionally, the level of hydrogen peroxide released by Reme Halo is a lot lower than the relevant FDA guidelines.

Is Ozone Safe?

Along with hydrogen peroxide, Reme Halo produces a small amount of ozone. While this molecule is safe, in high concentrations it can be harmful. This is why there are even people who are suspicious of Reme Halo warning you about it. 

Ozone, if ingested by humans, can cause symptoms such as coughing, lung irritation, and shortness of breath – bad news for those prone to illnesses. It may also cause more serious symptoms for those with underlying lung conditions.

So, does this mean that Reme Halo is dangerous?

Hold your horses, this air purifier is approved by the FDA which means its production of ozone is within safety levels for rules on ozone exposure. According to the FDA, the same exposure limit is at 0.1 ppm (parts per million) in 8 hours and for constant exposure in closed spaces this level is at 0.05 ppm.

In other words, Reme Halo is safe according to federal standards and its ozone emissions are minuscule. 

When Can Ozone Become a Serious Problem?

Even though the ozone emitted by Reme Halo is minuscule, depending on other factors, this air purifier could contribute to pushing the concentration of ozone in your home to dangerous levels.

Here are the factors to consider:

1. Underlying health conditions

Before purchasing a Reme Halo, consider if anyone in your home suffers from certain lung-related conditions. Although the ozone produced by this device is small, it may still be enough to exacerbate your sick family members’ symptoms.

To ensure everyone stays safe, consult your physician before installing a Reme Halo.

2. Is your home properly ventilated?

When ozone-producing appliances such as Reme Halo Led are combined with improper ventilation, levels of ozone in your home could quickly rise above harmless levels. This is because poor ventilation makes it impossible for ozone to escape, leading to buildup.

Check for signs of ventilation issues such as significant noticeable moisture on windows and other surfaces. Also, consider if you had any problems with mold in the past.

If the ventilation in your home is poor, you should first address this problem before even purchasing an air purifier.

3. Do you have any other ozone-producing appliances?

Before purchasing an air purifier, you should first consider other sources of ozone. That way, you can ensure you’re keeping ozone levels in your home at healthy levels.

The devices that also produce ozone are plentiful, and even innocent items like vegetable and fruit washers, laundry water treatment devices, and facial steamers all produce noticeable amounts of ozone. The same applies to electric fans, some hair dryers, printers, as well as copiers.

In most cases, since these appliances aren’t close to each other and usually aren’t running at the same time, you’re most likely safe.

We still recommend testing the amount of ozone to be on the safe side. You can purchase an expensive ozone monitor, or buy cheap ozone test strips on Amazon. This helps you determine with 100% certainty that Reme Halo won’t be a health hazard.

Is There An Air Purifier That Doesn’t Produce Ozone?

So you want to increase the quality of air in your home, but you don’t want to worry about your ozone levels? There is an option that outperforms the standard Reme Halo on almost all fronts (it’s more energy efficient) – Reme Halo LED.

Reme Halo LED is the ‘’new and improved’’ version of the basic air purifier and it produces no ozone. This version is a bit more expensive, but when you consider lower energy costs and the fact it doesn’t introduce any ozone into your home, it’s worth it.

Call Aztil Air Conditioning at +561-559-2205 if you want to purchase and install Reme Halo LED. We can be there in record time and ensure your air is as clean as possible!

Dana, my service tech did an amazing job to keep my AC up and running. He contacted me on his i, and was here in a flash.

He also updated me on the condition of the AC for the future, made some recommendations for me to consider.

Yesterday no ac!! Yikes. Dana was the technician who did not leave our house until he discovered and fixed the problem. Believe me, he missed dinner and this was a Friday night. Couldn’t be happier. Dana was so professional and knowledgeable. So happy we bought from Aztil and have a service contract with them. If you ever think it’s not worth having the service contract in case of emergency, when you have no ac and it’s sweltering outside, you will be so happy you made a smart decision! Thank you Dana and Aztil.

I've been using Aztil for over 20 years across 4 homes in Florida. From general services to complete A/C replacements, I wouldn't trust anyone else. My recent service in Port St. Lucie with Nico was excellent and he was very helpful in going over all of my HVAC system and answered a few questions I had.
I highly recommend Aztil for any HVAC issues or general maintenance.
Response from the owner:Hi Ralph, thank you for your kind words! We're so glad to hear that Niko did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
I cannot speak highly enough of our super kind technician, Randy, who came out to assess our AC today. Randy took the time to walk us through photos of the issues in our AC and offered to take care of it ASAP as he already had the parts in his truck - LOVE the preparedness! Aztil Air Conditioning is superior and we will request Randy on a go forward basis.

UPDATE 6/17/25 - Exceptional Service from True Professionals - Highly Recommend!

We recently had our ducts cleaned and sealed, plus our dryer vent serviced by Jordan and Hero from Aztil Air Conditioning, and I cannot say enough good things about their work. From the moment they arrived, these two demonstrated exactly what professional service should look like.

What impressed us most was their commitment to education - they took the time to walk both my husband and me through every step of the process, explaining not just what they were doing, but why it mattered for our home's efficiency and air quality. It's rare to find technicians who are so patient and thorough in their explanations.

Beyond their technical expertise, Jordan and Hero showed genuine respect for our home and our comfort level throughout the entire job. They worked with care and consideration, treating our space as if it were their own. As homeowners, we've all had those experiences where workers leave you feeling uneasy - this was the complete opposite. We felt completely at ease having them in our home.

Their professionalism, kindness, and attention to detail set them apart in an industry where those qualities aren't always guaranteed. If you're looking for HVAC services you can trust, don't hesitate to call Aztil Air Conditioning. Jordan and Hero will take excellent care of you and your home.

Five stars - we'll definitely be calling them for any future needs!
Response from the owner:Thank you Jessica for your positive feedback. I'm glad you were happy with the support we provided. Please keep us in mind for any HVAC needs.
Rick was terrific. Knowledgeable fast, courteous. We hope if we need a/c work, he's the one who comes out.

Thanks to Aztil AC! One of our A/C units broke down unexpectedly, and Anthony got Lazaro out to us right away the next morning.

Response from the owner:Hi Justin, thank you for your kind words! We're so glad to hear that Dana did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
The AC maintenance service was excellent. Niko Garza was professional, helpful, kind, and was instrumental in arranging for the next Senior Technician to solve the AC problem that I am having. That service will be sometime today. He also recommended the dryer vent cleaning and the in-line AC cleaning, of which I scheduled for Monday and paid today. My husband has been very ill for the past 4 years and in the hospital right now. Aztil has arranged the services, after Niko explained the situation, so that they will be completed before he comes home because a patient on oxygen and a feeding tube cannot be without power to the whole house, even a short shut down would endanger him. Thank you Niko!

Technician Rick Cochran did an excellent job replacing the AC breaker and ensuring that everything was in correct working condition. I really appreciated his kindness and professional demeanor. Thank you Rick!

Today Technician Alex Molina completed the services (dryer lint trap cleaning and inline air handler cleaning). Once again, I was fortunate to have a professional, gracious, and thoughtful person come to my house to perform the services. Thank you so much Alex!

June 2 2025 Thank you Cody! It is a relief to finally have the A/C back to what it should be. The replacement of the coil is probably what was needed a month ago. Rather than dwell on what was, I truly appreciate the replacement service and how kind you were to a grieving widow.
Response from the owner:Hi Admonis, thank you for your kind words! We're so glad to hear that Niko did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
Angel and his crew
Response from the owner:Hi Don, thank you for your kind words! We're so glad to hear that Angel did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
Tino Costanzo did an excellent job. Extremely helpful in adding to the efficiency of the operation of our air conditioning unit.
Response from the owner:Hi David, thank you for your kind words! We're so glad to hear that Tino did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
This is the second time Michael King has serviced my AC for AZTIL. He is always pleasant and courteous. He explains all he does to the unit and answers all questions I may have. He is very thorough. Great asset to the company. The trainee (Skyler) with him today has a very good teacher and seems to be on his way to being a positive service tech.
Response from the owner:Hi Walter, thank you for your kind words! We're so glad to hear that Michael and Skyler did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
Response from the owner:Hi Steven, thank you for your kind words! We're so glad to hear that Aztil did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
Lazaro was excellent. Full explanation of services. I would like to get him for any future services. I'd like to add that I was pleased with the vent cleaning that was performed by Alex Molina and his assistant.
Response from the owner:Hi Jazziz, thank you for your kind words! We're so glad to hear that Lazaro did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
I had woken up to no ac in my house. I contacted aztil on a Saturday at 5 pm and their technician called me back within a half hour. His name was Tino, he said that he would be there within 30 minutes…. And he was! He figured out the problem in 10 minutes and he solved it! Excellent service! Thank you so very much!
Response from the owner:Hi Patricia, thank you for your kind words! We're so glad to hear that Tino did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
