Which is better, the Aprilaire 5000 or an Aprilaire 2000-series air purifier?
For most Minnesota homes, a 2000-series media cabinet with a MERV 13 filter. It has no electrical parts, needs one filter change a year, and Aprilaire's own filter claims put it close to the 5000. The electronic 5000 mainly makes sense if you already own one and keep up with its extra upkeep.
Key points
- The Model 5000 is Aprilaire's electronic air purifier: nine ionizer wires charge the air so its 6-inch filter catches more.
- The "2000" is a family of passive media cabinets (2200, 2400, 2210, 2410, 2216), not one model.
- By Aprilaire's own filter claims, a MERV 13 or MERV 16 filter in a 2000-series cabinet is in the same league as the 5000.
- Aprilaire's once-a-year, no-tools maintenance note for its purifiers specifically excludes the Model 5000.
- Either cabinet only works if the return duct and blower can handle it, so airflow gets checked first.
For most Minnesota homes, we'd pick a 2000-series media cabinet with a MERV 13 filter over the electronic Model 5000. The media cabinet has no electrical parts, needs one filter change a year, and by Aprilaire's own filter claims now lands close to the 5000. The 5000 makes sense mainly if you already own a working one and keep up with its extra maintenance.
Aprilaire, the Madison, Wisconsin company that also makes whole-home humidifiers, names these products in a way that trips people up. The Model 5000 is one specific product: an electronic air purifier. "The 2000" isn't a single model. It's Aprilaire's family of passive media cabinets, the 2200, 2400, 2210, 2410 and 2216. Both kinds bolt into the return duct next to your furnace, both hold a deep pleated filter, and from the basement stairs they look nearly the same. The difference is what happens inside the box and what you have to do to keep it working.

What are the Aprilaire 5000 and 2000-series air cleaners?
The Model 5000 is a galvanized steel cabinet sized for a nominal 16x25 opening. It holds Aprilaire's 6-inch 501 filter, and in front of that filter sit nine tungsten ionizer wires. When the unit is powered, those wires electrify the air around the filter so passing particles pick up a charge and stick to the media more readily. Without power, it's a 6-inch filter in a box.
The 2000 series has no electrical parts at all. It comes in two generations:
- 2200 and 2400: the older cabinets, which take 6-inch MERV 10 media (the 201 and 401) held open by plastic pleat spacers.
- 2210, 2410 and 2216: the current generation, with 4-inch filters that slide into interlocking rails and seal against the cabinet. The 2210 and 2410 ship with MERV 13 filters (the 213 and 413). The 2216 ships with a MERV 16 filter. The 2210 family takes 20x25 filters, the 2410 family 16x25.
Aprilaire has also started moving these cabinets to a newer U-series line that uses 3-inch filters.
Filtration, by Aprilaire's own numbers
This table uses Aprilaire's product claims for each filter. Keep in mind these are manufacturer figures from different test setups, so read them as a rough comparison, not a head-to-head lab result.
| Filter | Fits | What Aprilaire claims |
|---|---|---|
| 501 | Model 5000 | Equivalent to MERV 15 when used in the 5000. Up to 90% of virus-size particles, up to 98% of airborne allergy and asthma triggers |
| 213 / 413 | 2210 / 2410 families | MERV 13. Up to 97% of common allergens and 92% of viruses (ASHRAE 52.2 test using the MS-2 virus) |
| 216 / 416 | 2210, 2216 / 2410 families | MERV 16. 98% of airborne viruses, up to 99% of allergy and asthma triggers |
The takeaway: the electronic cabinet's edge over good media has shrunk. Back when the media cabinets ran MERV 10 filters, the 5000 was the clear step up. Today a MERV 13 or 16 filter in a passive cabinet makes the same kind of claims without wires or a power cord. If the MERV numbers themselves are fuzzy, our guide to MERV ratings for allergies walks through what each level catches.
On smoky summer days, when Canadian wildfire smoke settles over the state, the fine particles are the ones under 1 micron. Under the ASHRAE test, a MERV 13 filter has to catch at least 50% of particles from 0.3 to 1.0 micron, and a MERV 16 at least 95% (EPA's MERV table). Whatever you own, set the thermostat fan to "on" during smoke events. A filter only cleans the air that moves through it.
How does maintenance differ on the Aprilaire 5000 and 2000?
A 2000-series cabinet is about the easiest maintenance in the basement. Open the door, slide the old filter out, slide a new one in. Aprilaire rates its 213 and 413 filters for up to 12 months, and says to change the MERV 16 filter in a 2216 up to every 6 months. Aprilaire's own FAQ describes the annual job as taking under a minute, with no tools, washing or vacuuming, and then carves out one exception: the Model 5000.
The 5000 has more parts to look after. On top of the 501 filter, the ionizer wires, pleat spacers and door seal are all sold as replacement parts, and the ionizing section has to be kept clean per the owner's manual. A broken or dirty wire doesn't stop air from flowing. It just quietly turns the 5000 into an ordinary 6-inch filter, which is why we check the power light and look at the wires when one comes up on a maintenance visit.
A Minnesota house spends about six months closed up, so from October to April the furnace filter does nearly all of the air cleaning. Dust, pet dander and cooking particles have nowhere else to go, and the filter loads faster in a winter with the blower running long hours. Check it midwinter even if the label says 12 months.
Where does an Aprilaire cabinet go on the furnace?
Either cabinet goes in the return, right before the furnace. A deep filter has far more surface area than a 1-inch filter, so at the same MERV it restricts much less air. That doesn't make the return big enough by itself. Plenty of Minnesota houses were built with one undersized return, or with panned joist bays standing in for return ducts, and those are already short of air before anyone adds a MERV 16 filter.
Before we recommend either unit we measure static pressure, then check it again with the new filter in place. Starve a furnace of return air and it runs hot and trips its limit switch; starve the AC and the coil can ice up in July. The cabinet also has to match the opening, so a 16x25 unit and a 20x25 unit aren't interchangeable. The cleanest time to add one is during a furnace replacement, when the return plenum is being rebuilt anyway.
What does installing an Aprilaire cabinet involve?
Adding a cabinet to an existing furnace is usually a short job. The order we follow:
- Measure static pressure with the current filter in place.
- Pick the cabinet size that matches the return opening.
- Cut it into the return right before the furnace, with room to slide the filter out.
- Seal the cabinet to the duct so air can't sneak around the filter.
- Wire power if it's a Model 5000.
- Measure static pressure again with the new filter in.
How much do the Aprilaire 5000 and 2000 cost installed?
National cost guides like HomeGuide put an extended-media cabinet at $400–$800 installed and electronic air cleaners at $500–$2,000. Our own installed range for air quality equipment is $350–$2,800, and every job gets a written flat-rate quote before any work starts. Replacement filters are an ongoing cost with either one; count on a filter a year for the MERV 13 cabinets, and more often for MERV 16 or the 5000. If a furnace replacement in Minneapolis or elsewhere is coming, add the cabinet then.
Which one we'd put in
- Most houses: a 2000-series or current U-series cabinet with a MERV 13 filter. It handles dust, dander and pollen, needs one filter change a year, and has nothing to break.
- Allergy or asthma in the house: MERV 16 media if the static pressure allows it, changed on the shorter schedule. For households that also want odor control, it's worth comparing against a filter-plus-PCO system like Lennox PureAir.
- Cooking or pet odors: neither cabinet does much for gases with standard media. Aprilaire sells carbon versions of its MERV 13 filters (the 213CBN and 413CBN) for that.
- You already own a working 5000: keep it, keep the wires clean, and replace the 501 on schedule. There's no need to swap a working unit.
Our air purification service covers media cabinets, electronic cleaners and UV, and whole-home humidifiers mount on the same furnace if dry winter air is part of the complaint.
What to do next
Pull your filter and read the number printed on it, then check the date you wrote on it last time (or didn't). If you want the airflow checked before an upgrade, we can do it during a furnace or AC tune-up, and our indoor air quality page covers the rest of the equipment we work on. For the bigger picture on winter air, see our guide to indoor air quality in a Minnesota winter. If the furnace starts tripping its limit switch or the AC coil ices after a filter upgrade, stop using the new filter and call. The $79 trip charge is waived when you approve the repair. Call 612-429-3465, any day from 7am to 9pm.
Questions
Does the Aprilaire 5000 produce ozone?
It may make a small amount. Devices that charge particles with high voltage can produce some ozone as a by-product, and EPA says as much about ionizers in general. The Aprilaire product pages we checked for the 5000 don't publish an ozone figure, so ask for the current documentation if ozone matters to you. A 2000-series media cabinet has no power connection at all, so it makes none.
Can I put a MERV 16 filter in my Aprilaire 2210?
Yes. Aprilaire lists its 216 MERV 16 filter as compatible with the 2210, and sells the 2216 cabinet with that filter already in it. For the 2216, Aprilaire says to change the filter up to every 6 months instead of 12. MERV 16 media restricts more air, so have the static pressure checked before switching, especially on an older furnace with a small return.
What replaced the Aprilaire 2410?
Aprilaire's newer U-series cabinets. Its U243 16x25 purifier is listed as the replacement for the 2410 and uses a 3-inch MERV 13 filter. A working 2410 still takes the 410, 413 and 416 filters, so there's no reason to tear out a cabinet that's doing its job.
How do I tell which Aprilaire I have?
Read the number printed on the filter. A 201 or 401 is the older 6-inch media from a 2200 or 2400. A 210, 213 or 216 fits the 2210 family, and a 410, 413 or 416 fits the 2410 family. A 501 means you have a Model 5000. The cabinet also has a model label, usually on or inside the door.
