A Jupiter family reached out to us after years of dealing with allergies that never really seemed to let up. Both kids were waking up congested every morning. Mom and dad were getting headaches that seemed to track with how long they'd been inside. Over-the-counter antihistamines weren't doing much. Deep-cleaning the carpets hadn't moved the needle. The pediatrician had asked about indoor air quality at the last visit, and that was the moment they decided to actually look at what was happening in the air they were breathing inside their own home.
When our tech went out for an indoor air quality assessment, he found a setup that's depressingly common across Florida homes built in the last twenty years. Original AC equipment installed in the late 2000s. A basic MERV 6 filter that wasn't catching much beyond visible dust. Dusty coils that hadn't been cleaned since the system was put in. Zero whole-home purification of any kind. And in a Florida home where the AC runs nine to ten months out of the year, every cubic foot of air in the house cycles through that air handler dozens of times a day. If the system isn't actively cleaning the air, it's actively recirculating whatever's in it.
First, we installed a REME HALO whole-home purification system inside the air handler. REME HALO is a small unit that mounts in the supply plenum and uses a hydroperoxide reaction to neutralize airborne pollutants, allergens, mold spores, bacteria, and viruses as the air cycles through. The treated air then gets distributed to every room the AC reaches, which means every bedroom, the kitchen, the living areas, all of it. Unlike portable air purifiers that only clean the room they're in, a REME HALO treats the whole house.
Second, we upgraded the filter to MERV 13. The original MERV 6 filter was rated to catch lint and visible dust but not much else. MERV 13 catches finer particulates, including pollen, pet dander, mold spores, smoke particles, and the kind of microscopic allergens that drive chronic congestion. The system was rated to handle the slightly higher static pressure of a MERV 13 filter without overloading the blower, which is something we always verify before recommending an upgrade. Pushing a high-MERV filter through a system not rated for it just makes the blower work harder and cuts airflow, which makes IAQ worse not better.
Third, we adjusted the thermostat and air handler settings to manage humidity more aggressively. Damp Florida air carries airborne irritants farther and faster than dry air does. By holding indoor humidity in the 45 to 55 percent range instead of letting it drift up to 60 percent or higher (which is common in older Jupiter homes with leaky envelopes), we cut down on both the airborne particulate load and the conditions that mold and dust mites need to thrive.
About ten days after the install we got a text. The kids weren't waking up congested anymore. The morning headaches had faded. The family was noticeably better. That's the REME HALO doing what it's supposed to do, combined with the MERV 13 filter catching what slipped past the purifier, combined with the lower humidity making it harder for everything to thrive in the first place. We followed up at 30 days for a maintenance check and the family reported the difference had held.
Florida humidity is the single biggest reason indoor air gets stale, mold-prone, and allergy-triggering. Most Treasure Coast homes were never designed to filter or actively ventilate properly. They were designed to be sealed boxes with cold air pumped through them. That works for cooling. It doesn't work for indoor air quality. If anyone in your household struggles with chronic congestion, allergies, asthma, frequent headaches at home, or just feels worse indoors than outdoors, the air handler is the first place to look.

We'll measure what's actually in the air and recommend the right combination of purification, filtration, and humidity control for your specific situation.
