Honeywell 115369 vs Honeywell Home X8S: Filter or Thermostat?
These two products share a brand name and nothing else. The Honeywell 115369 is a two-pack of reusable pre-filters for Honeywell air cleaners, while the Honeywell Home X8S is a premium smart Wi-Fi thermostat with a touchscreen. The keyword pairs them, but the purchase decision is really about which job needs solving first: air filtration upkeep or whole-home climate control. The short answer sits in the overview table below, and the full breakdown follows.
The Picks at a Glance
| Product | Key Spec | Best Use | Price Tier |
|---|---|---|---|
| Honeywell 115369 (2-pack) | Reusable pre-filter, 12.5 x 20 in | Replacing clogged pre-filters in compatible Honeywell air cleaners | Budget |
| Honeywell Home X8S | 5" touchscreen, Wi-Fi, Matter, Alexa/Apple/Google | Upgrading to a smart thermostat with multi-platform control | Premium |
The 115369 is a consumable-replacement purchase — cheap, specific, and only useful if a compatible air cleaner already sits in the home. The X8S is a hardware upgrade that changes how the whole house is heated and cooled.
Honeywell 115369 F50F F300 Air Pre-Filter (2-Pack)
Type: Reusable air cleaner pre-filter
Pack Size: 2-pack
Dimensions: 12.5 x 20 in
Compatibility: Honeywell air cleaner models 203369, F50E1349, F50E1331, F50E1067, F50F1057, F50A1116, F50F1040
Construction: Washable, reusable media
Intended Use: Pre-filtration ahead of the main filter
This is the outer layer of a Honeywell air cleaner’s filtration stack. The pre-filter catches larger debris — dust, hair, lint — before it reaches the main filter, which extends the life of the more expensive media behind it. Because it is reusable, the maintenance routine is wash, dry, reinstall rather than buy, replace, repeat.
The two-pack matters more than it looks. One filter goes in the unit while the other dries after washing, so the air cleaner never runs without pre-filtration during cleaning. Buyers who already own one of the listed Honeywell air cleaner models get a direct-fit part; everyone else should check the model number on the unit before ordering.
Trade-off: The 12.5 x 20 in size and model-specific compatibility mean this filter is useless to anyone whose air cleaner is not on the compatibility list — it is a replacement part, not a universal accessory.
Honeywell Home X8S Premium Smart Wi-Fi Thermostat
Type: Smart Wi-Fi thermostat
Display: 5" touchscreen
Smart Home: Works with Alexa, Apple, Google, Matter
Feature: Humidity control
Certification: Energy Star
Color: White
Intended Use: Whole-home heating and cooling control
The X8S is the premium end of Honeywell Home’s thermostat line. The 5-inch touchscreen is the interface, and the Matter support is the important spec: it lets the thermostat join a smart home ecosystem without locking the buyer into one platform. Alexa, Apple, and Google compatibility all sit on top of that.
Humidity control separates it from a basic programmable thermostat — managing moisture alongside temperature matters in both summer cooling and winter heating. Energy Star certification points to efficiency as a design goal rather than an afterthought. This is a device for a household that wants scheduling, remote control, and voice commands in one unit.
Trade-off: At the premium tier, the X8S costs more than a straightforward programmable thermostat, and the full feature set — Matter, humidity control, app scheduling — only pays off for buyers who will actually use smart-home integration.
Side-by-Side Comparison
| Dimension | Honeywell 115369 | Honeywell Home X8S |
|---|---|---|
| Product Type | Reusable air cleaner pre-filter | Smart Wi-Fi thermostat |
| Pack Size | 2-pack | Single unit |
| Dimensions | 12.5 x 20 in | Not applicable |
| Display | None | 5" touchscreen |
| Smart Home | None | Alexa, Apple, Google, Matter |
| Humidity Control | No | Yes |
| Energy Star | No | Yes |
| Reusability | Washable and reusable | Permanent installation |
| Price Tier | Budget | Premium |
| Installation | Swap into existing air cleaner | Replaces existing thermostat |
The table reads cleanly along one line: these products do not compete. The 115369 is a consumable that keeps an existing appliance running; the X8S is an appliance that replaces an existing control device.
Where the comparison does carry weight is in maintenance philosophy. The 115369 is reusable, so its cost is a one-time spend that recurs only if the filter wears out. The X8S has no consumable, but it asks for a bigger upfront commitment and rewards it over years of scheduling and efficiency.
The third dimension is compatibility. The 115369 only works with the listed Honeywell air cleaner models — a narrow, verified fit. The X8S works with the major smart home platforms through Matter, which is the broadest compatibility either product offers.
Which Should You Buy?
Choose the Honeywell 115369 if: a Honeywell air cleaner already sits in the home and its pre-filter is clogged, torn, or missing. The two-pack keeps a spare on hand during wash cycles, and the price tier makes it an easy maintenance purchase.
Choose the Honeywell Home X8S if: the goal is upgrading climate control — replacing an old thermostat with one that supports scheduling, voice commands, humidity management, and Matter-based smart home integration. The premium price buys features that only matter to households that will use them.
The two do not overlap. A buyer who needs both should buy both; a buyer deciding between them should first identify which appliance is actually due for attention.
FAQ
-
Are the Honeywell 115369 and Honeywell Home X8S compatible with each other?
No. One is an air cleaner pre-filter and the other is a thermostat. They serve different systems in the home and do not interact. -
Does the Honeywell 115369 fit every Honeywell air cleaner?
No. It is sized at 12.5 x 20 in and listed for specific models including 203369, F50E1349, F50E1331, F50E1067, F50F1057, F50A1116, and F50F1040. The model number on the unit should be checked before ordering. -
Is the Honeywell 115369 really reusable?
Yes. The filter is washable, which is why the two-pack is useful — one filter runs while the other dries. -
What makes the Honeywell Home X8S a premium thermostat?
The 5-inch touchscreen, Matter support, Alexa/Apple/Google compatibility, humidity control, and Energy Star certification together place it above basic programmable models. -
Does the X8S need a smart home hub?
Matter is designed to work across platforms, and the thermostat also lists direct Alexa, Apple, and Google support. A hub may still be required depending on the specific ecosystem setup. -
Which product is the better value?
They are not comparable on value. The 115369 is a low-cost maintenance part; the X8S is a long-term home upgrade. Value depends on which job the buyer needs done. -
Can the X8S control humidity without separate equipment?
The thermostat includes humidity control as a feature. Whether it can manage humidity independently depends on the HVAC system it is connected to.
Bottom Line
These are not alternatives — they are different purchases wearing the same brand. The Honeywell 115369 is the right buy for anyone maintaining a compatible Honeywell air cleaner, and the two-pack makes the wash-and-swap routine practical. The Honeywell Home X8S is the pick for a household ready to upgrade its thermostat to a smart, Matter-compatible, humidity-aware unit. Match the product to the appliance that needs attention, and the decision takes under a minute.
