Rheem air filters are standard pleated HVAC filters sized to fit your Rheem central air, heat pump or air handler — Rheem does not use one universal size, so the filter you need depends on your system's return, not the brand name. The most common Rheem filter sizes in Miami homes are 16x25x1, 20x25x1, 20x20x1, 16x20x1 and 14x25x1. Air Duct Cleaning Miami stocks every Rheem size in MERV 8, 11 and 13, delivers free across Miami-Dade and Broward County, and installs them for you — first install free.

One of the biggest myths about Rheem filters is that there's a single “Rheem size.” There isn't. Rheem builds a wide range of systems — the Classic, Classic Plus and Prestige series of central air conditioners and heat pumps, plus matching RH-series air handlers — and the filter size is determined by the return-air opening on your specific unit or wall grille, not by the Rheem badge on the cabinet. Two homes can both run Rheem and need completely different filters.
The fastest way to know your size: pull out the filter you have now and read the three numbers printed on the cardboard frame — width × length × depth, like 16x25x1. If you can't find a filter, measure the slot opening in inches. Below are the sizes we see most often on Rheem systems across Miami-Dade and Broward. Tap any size to shop it on this page.
| Filter Size (W×L×D) | Typical Rheem System | Shop |
|---|---|---|
| 16x25x1 | Many Rheem upflow air handlers & smaller homes | |
| 20x25x1 | Larger Rheem central air & heat pump returns | |
| 20x20x1 | Common Rheem condo & townhome returns | |
| 16x20x1 | Compact Rheem air handlers & closets | |
| 14x25x1 | Older Rheem & Ruud systems, narrow returns |

On most Rheem systems the filter lives in one of two places. The first is a slot on the return-air side of the indoor air handler — typically a Rheem RH-series unit in a closet, garage, attic or utility room. Look for a removable filter door or a slide-out slot near where the large return duct connects to the unit; on Rheem upflow and horizontal air handlers it's usually at the bottom or side intake. The second common location is behind a return-air grille on a wall or ceiling — if your home pulls air through a large grille, the filter slides in right behind it. Some Rheem setups with a media-air-cleaner cabinet hold a thicker 4-inch filter in a dedicated housing next to the air handler.
Every pleated filter has an airflow arrow printed on the side, and it must point toward the blower / air handler — the same direction air is being pulled into the system, away from the return duct and toward the coil or furnace. In a Rheem air handler the arrow points toward the unit; behind a wall or ceiling return grille, the arrow points into the wall or ceiling. Installing a filter backwards collapses the pleats, restricts airflow and lets dust slip past — a small mistake that strains the blower and shortens the life of your Rheem system. When our technician installs your filter, we set the arrow correctly every time.
Rheem residential systems are designed around standard 1-inch filters, so the everyday sweet spot is MERV 8 to MERV 11. Go higher only when you have a reason — pets, allergies or asthma — and watch the airflow. Pushing a dense MERV 13+ filter into a standard 1-inch Rheem return can restrict airflow enough to ice the coil or overwork the blower motor. If you want hospital-grade filtration on a Rheem system, the right move is a 4-inch media filter in a media-air-cleaner cabinet, which delivers high MERV without choking airflow. Not sure which way to go? Our AC maintenance team can check your Rheem's static pressure and recommend the safe maximum.
Everyday dust, pollen and pet dander. The safe default for most Rheem systems.
Step up for pets, kids or mild allergies on a Rheem AC or heat pump.
Fine particles, smoke and allergens — best in a 4-inch Rheem media cabinet.

A dirty filter is the #1 cause of avoidable Rheem AC breakdowns in Florida — the U.S. Department of Energy reports a clogged filter can raise HVAC energy use 5–15%. On a Rheem system running year-round in Miami heat, a $7 filter pays for itself fast. Need more than filters? See our AC repair and air duct cleaning services.

South Florida is brutal on filters. Humidity, year-round pollen and constant AC runtime clog them faster than anywhere else. Here’s the right schedule.
A clogged filter forces your AC to work harder — the U.S. Department of Energy says a dirty filter can raise energy use 5–15%. In Florida, where AC is 40%+ of your electric bill, a $7 filter pays for itself. Not sure what your home needs? Our AC maintenance team can set your ideal schedule.

“I used to forget my filters for months. Now they come to my door on a schedule and the tech swaps it in five minutes. The MERV 11 they recommended cut down my allergies big time. Way easier than ordering a box online.”
“I manage 12 rental units in Doral. They deliver the right filter to each unit on a quarterly schedule and install them too. One vendor, one invoice, every unit covered. Saves me a full day every month.”
“My mom can’t reach her filter in her Hallandale condo. They bring the right MERV 11 for her allergies, install it, and check her AC every visit. Peace of mind for me, clean air for her.”
