AprilAire Model Compatibility Guide
Not sure which Aerostar replacement filter fits your AprilAire system? Use the table below to match your filter model or air cleaner unit number to the right Aerostar replacement. Each filter is engineered as a direct, drop-in replacement — same dimensions, same fit, at a lower cost.
| Filter Model | MERV | Compatible Units | Size | Depth | OEM MERV |
|---|---|---|---|---|---|
| 410 | 11 | 2400, Space-Gard 2400 | 16×28 | 4 inch | 11 |
| 413 | 13 | 2400, Space-Gard 2400 | 16×28 | 4 inch | 13 |
| 213 | 13 | 1210, 1620, 2210, 2216, 3210, 4200 | 20×26 | 4 inch | 13 |
| 210 | 11 | 2200, Space-Gard 2200 | 20×26 | 4 inch | 11 |
| 201 | 8, 11 | 2200, Space-Gard 2200 | 20×25 | 6 inch | 10 (OEM) |
| 401 | 8, 11 | 2400, Space-Gard 2400 | 16×28 | 6 inch | 10 (OEM) |
Note: The OEM AprilAire 201 and 401 are rated MERV 10. Our Aerostar replacements for these systems are available in MERV 8 (for basic dust protection) and MERV 11 (for enhanced filtration). Both fit the same 201/401 cabinet dimensions.
Looking for a model not listed here, such as the AprilAire 110, 310, or 216? Contact us at 877-492-3018 — we may be able to source it or recommend a compatible alternative. Browse our full selection of 4-inch filters for additional options.
Choosing the Right MERV Rating for Your AprilAire System
MERV (Minimum Efficiency Reporting Value) measures how effectively a filter captures airborne particles. Higher ratings trap smaller particles but also increase airflow resistance. AprilAire's deep-pleat systems (4-inch and 6-inch) handle higher MERV ratings with far less restriction than standard 1-inch filters.
| MERV Rating | What It Captures | Best For |
|---|---|---|
| MERV 8 | Dust, pollen, dust mites, mold spores | Standard homes, equipment protection |
| MERV 11 | All of MERV 8 + pet dander, auto emissions, fine dust, smoke | Pet owners, mild allergies, homes near highways |
| MERV 13 | All of MERV 11 + virus carriers, bacteria, smog, wildfire smoke (PM2.5) | Severe allergies, asthma, wildfire areas |
Unlike OEM AprilAire filters — which lock each model number to a single MERV rating — Aerostar replacements from Air Filters Delivered give you the flexibility to choose. Have a Space-Gard 2400 system? You can run a MERV 11 (Model 410 equivalent) or upgrade to MERV 13 (Model 413 equivalent) using the same 16×28×4 Aerostar filter. Not sure which rating to pick? Read our guide: How Do You Know What MERV Rating to Use?
Why Choose Aerostar Over OEM AprilAire Filters?
When it's time to replace the filter in your AprilAire system, you have three main options: buy the original OEM filter from AprilAire, order from a competitor like Filterbuy, or go factory direct with Aerostar from Air Filters Delivered.
| Feature | Aerostar (Air Filters Delivered) | OEM AprilAire | Filterbuy |
|---|---|---|---|
| MERV Flexibility | Multiple MERV options per system | Fixed — one MERV per model # | Multiple options |
| Subscription Discount | 8% off every order | None | 5% off |
| Shipping | Free on all orders | Varies | Free (continental US) |
| Manufacturing | Made in USA (Orlando, FL) | Made in USA | Made in USA |
| Frame Design | Collapsible — folds for easy handling | Rigid frame | Standard frame |
| Return Policy | 30 days | Varies | 90 days |
Aerostar replacements use the same type of electrostatic synthetic pleated media found in OEM AprilAire filters, built to the same dimensions for a gap-free fit. The difference is price: buying factory direct from Air Filters Delivered skips the retail markup, especially when you combine bulk pricing with the 8% Subscribe & Save discount.
How to Install an Aerostar Collapsible Replacement Filter
Aerostar's collapsible frame design folds flat for compact shipping and storage, then expands to full depth when installed. Here's how to swap in a new filter:
- Turn off your HVAC system. Switch the thermostat to "Off" before opening the filter cabinet.
- Open the filter cabinet door. Locate the access panel on your AprilAire unit. Most models use a simple latch or swing door.
- Remove the old filter. Slide it out along the tracks. Note the airflow direction arrow on the frame.
- Unfold the Aerostar replacement. Gently open the collapsible frame to its full 4-inch or 6-inch depth.
- Slide the new filter into the tracks. Match the airflow arrow to the direction printed on the cabinet. Close the door and turn your system back on.
Takes about two minutes. No tools required. For more detail, see: How to Change Your Home Air Filter.
How Often Should You Replace Your AprilAire Filter?
Replacement frequency depends on filter depth, MERV rating, and household conditions:
| Filter Depth / Type | Standard Household | High-Use Household* |
|---|---|---|
| 4-inch MERV 11/13 (410, 413, 213, 210) | Every 6–12 months | Every 4–6 months |
| 6-inch MERV 8/11 (201, 401) | Every 9–12 months | Every 6–9 months |
*High-use: households with pets, allergy sufferers, smokers, heavy HVAC use, or wildfire-prone/high-pollen areas. Visual indicator: replace when the filter has changed from white to dark gray.
Never forget a filter change. Enroll in Subscribe & Save and we'll deliver fresh filters on the schedule you set — every 3, 6, or 12 months. Save 8% on every order. Adjust or cancel anytime.
Frequently Asked Questions About AprilAire Replacement Filters
Are Aerostar filters compatible with AprilAire systems?
Are Aerostar filters compatible with AprilAire systems?
Yes. Aerostar replacement filters are engineered as direct, drop-in replacements for AprilAire whole-house air purification systems. They match OEM dimensions exactly — no modifications needed. Use the compatibility table above to find the right filter for your specific AprilAire unit model (2200, 2400, 2210, 4200, etc.).
What is the difference between AprilAire 210 and 213?
What is the difference between AprilAire 210 and 213?
Both the AprilAire 210 and 213 are 20×26×4 filters designed for the same air cleaner units (models 1210, 1620, 2210, 2216, 3210, 4200). The difference is filtration level: the 210 is MERV 11 (captures pet dander, fine dust, and smoke) while the 213 is MERV 13 (adds virus carriers, bacteria, and wildfire smoke PM2.5). If you have allergies, asthma, or pets, the MERV 13 is the better choice. For standard homes, MERV 11 provides solid protection at a slightly lower price.
Can I use a different MERV rating than my original AprilAire filter?
Can I use a different MERV rating than my original AprilAire filter?
In most cases, yes. AprilAire's deep-pleat cabinets are designed to handle higher-MERV filters with less airflow restriction than 1-inch systems. If your system came with a Model 410 (MERV 11), you can upgrade to MERV 13 using the same 16×28×4 Aerostar filter. If you have an older system, contact us before upgrading.
Are AprilAire filters washable or reusable?
Are AprilAire filters washable or reusable?
No. AprilAire-compatible replacement filters are disposable. The pleated synthetic media cannot be effectively washed or vacuumed without damaging the fibers. Replace the filter on the schedule recommended for your depth and MERV rating.
What is the difference between nominal and actual filter size?
What is the difference between nominal and actual filter size?
Nominal size is the rounded measurement on the label (e.g., 16×28×4). Actual size is slightly smaller, so the filter slides into the cabinet without binding. When ordering, use the nominal size from your current filter or system manual. Our product pages list both dimensions.
How long does shipping take?
How long does shipping take?
All orders ship free via ground from our Orlando, FL manufacturing facility. Most orders arrive within 3–7 business days. Expedited shipping is not currently available for filter orders.
