Dyson Air Purifier Filter Guide 2026 — Replacement Cost, Models and Reset Instructions

Dyson Air Purifier Filter by Model — Compatibility Guide

Dyson filter compatibility is model-specific. Using the wrong filter breaks the housing seal and reduces filtration effectiveness. Confirm your model before purchasing.

Dyson TP07 (Purifier Cool, Tower)
Filter: Dyson TP07 Combined HEPA + Activated Carbon Filter (Part 970341-01 or similar).
This filter is a sealed unit combining H13 HEPA and activated carbon in a single cylindrical cartridge.
Replacement cost: $55–70.
Replacement interval: every 12 months at 12h/day (4,380 hours).
The TP07 is Dyson's Pure Cool tower purifier-fan combination. See the Dyson TP07 review for full performance analysis.

Dyson HP07 (Purifier Hot+Cool, Tower)
Filter: Dyson HP07 Combined Filter (Part 970087-01 or similar).
The HP07 adds heating functionality to the TP07 platform. The filter is the same sealed HEPA + carbon combination.
Replacement cost: $55–70.
Replacement interval: 12 months at 12h/day. See the Dyson HP07 review.

Dyson TP09 (Purifier Cool Formaldehyde)
Filter: Dyson TP09 Combination Filter (includes HEPA + activated carbon + catalytic formaldehyde destruction filter).
The TP09 adds a solid-state catalytic filter that destroys formaldehyde by converting it to CO2 and water. This catalytic filter is permanent — it does not require replacement as it is self-regenerating. Only the HEPA + carbon portion of the TP09 filter assembly requires periodic replacement.
Replacement cost: $60–75 for the HEPA + carbon module.
Replacement interval: 12 months at 12h/day.

Dyson TP10 / HP10 (Purifier Big + Quiet Formaldehyde)
Filter: Dyson TP10 Filter (larger format to match the 10L/s airflow capacity).
The TP10 is Dyson's highest-CADR residential unit. The filter is a larger format version of the sealed HEPA + carbon design.
Replacement cost: $65–80.
Replacement interval: 12 months at 12h/day.

Older Models — TP04, HP04, DP04
Pre-2021 Dyson purifiers (TP04, HP04, DP04) use a different filter format — split into two separate cylindrical filters rather than a single combined unit. These are still available at dyson.com but are being phased out. Confirm the generation of your unit before ordering. The TP04 filter is not compatible with the TP07 housing and vice versa.

How to Replace a Dyson Air Purifier Filter

Dyson filter replacement is a quick 5-minute process. The procedure is consistent across current-generation TP07, HP07, TP09 and TP10 models.

Step 1 — Power Off Using the Standby Button
Press the standby button on the remote control or the Dyson app to power off the unit. Unplug from the mains. The unit must be unplugged before filter access — there is no mechanical interlock, but the filter housing releases more easily when power is off.

Step 2 — Twist and Remove the Filter Shroud
On tower models (TP07, TP09), grip the base of the unit and twist the filter shroud counterclockwise (looking down from the top). The shroud unlocks and can be lifted up and off, revealing the cylindrical filter inside.

Step 3 — Remove the Old Filter
The filter sits on a central spindle. Lift it straight up and out. Dispose in household waste — do not attempt to clean or reuse. The used filter contains captured particles; carry it to a bin directly.

Step 4 — Insert the New Filter
Remove the new filter from its packaging. Lower it onto the central spindle in the correct orientation — an arrow or alignment mark on the filter aligns with a mark on the base. Press firmly down until the filter seats completely.

Step 5 — Reattach the Shroud and Plug In
Lower the filter shroud over the filter and twist clockwise to lock. Plug in the unit and power on.

Step 6 — Reset the Filter Life Counter
The filter life counter must be reset after replacement. Method 1 (recommended): Open the MyDyson app, go to your device, select the filter icon and tap "Reset filter life." Method 2 (remote): Hold the standby button on the remote for 6 seconds until the filter life indicator resets in the Dyson display (where fitted). On models without a display, the app method is the only option.

Dyson Filter Cost and Where to Buy

Dyson replacement filters are premium-priced compared to other brands. Understanding your options reduces the ongoing cost of Dyson ownership.

OEM Dyson Filters — Official Sources
dyson.com: Full RRP, typically $55–80 depending on model. Includes Dyson warranty coverage and guaranteed compatibility.
Amazon (sold by Dyson): Same price as dyson.com, often eligible for Prime shipping.
Best Buy, Target: Stock current-generation Dyson filters in-store and online at similar prices to dyson.com.

Compatible Third-Party Filters
Third-party Dyson-compatible filters are available on Amazon at $25–45 — typically 30–50% cheaper than OEM. Quality concerns for Dyson filters are more significant than for other brands because: (1) Dyson's sealed HEPA design relies on the filter-to-housing seal integrity, which must match the OEM dimensional spec precisely; (2) Dyson's catalytic formaldehyde layer in TP09 and HP09 filters cannot be replicated by third parties. For models with the standard HEPA + carbon filter (TP07, HP07), third-party options are more viable — look for filters explicitly listed for your model number, with HEPA grade certification and verified dimensional specifications. A filter that does not seat correctly against the housing creates a bypass leak regardless of its stated filtration rating.

Dyson Annual Filter Cost vs Competitors
Dyson TP07 annual filter: $55–70 for one filter per year.
Levoit Core 400S annual filter: $20–30 for one filter per 6–8 months = $35–60 per year.
Winix 5500-2 annual filter: $25–35 for HEPA + carbon, typically one set per year = $25–35 per year.
Dyson's filter premium is approximately $20–30/year over Levoit and $30–45/year over Winix. Over 5 years: $100–225 additional filter cost for the Dyson premium. Buyers should factor this into the total ownership cost calculation when comparing Dyson against alternatives.

Dyson Filter Life — When to Replace and What Affects It

The Dyson filter life system tracks operating hours and calculates replacement timing. Understanding how usage affects filter life helps optimize the replacement schedule.

Standard Replacement at 4,380 Hours
Dyson calculates 12 months at 12 hours per day = 4,380 operating hours. The MyDyson app displays the remaining filter life as a percentage and time estimate. If you run your Dyson purifier at 8 hours per day, the filter life will extend to approximately 18 months (4,380 ÷ 8 ÷ 365 × 12 = 18 months). If you run it 24/7, filter life drops to approximately 6 months.

Factors That Accelerate Filter Loading
Pets: cat and dog dander load the HEPA layer faster, particularly in small rooms with multiple pets. High fan speed: maximum airflow draws more particle mass per hour through the filter. High-pollution environments: homes near major roads, high-pollen areas or active wildfire zones during events accumulate particle load faster. Cooking: PM2.5 spikes from cooking (particularly at high heat with oil) accelerate carbon saturation. In these conditions, visually inspect the filter outer surface at 8–10 months and consider early replacement if the filter surface appears heavily loaded.

The Sealed HEPA Design — Why It Matters
Dyson's purifiers use a sealed filter system that Dyson claims eliminates air bypass — all air drawn through the unit passes through the HEPA filter. Many standard HEPA purifiers allow small air bypass volumes around filter frame edges. The sealed design is a genuine quality claim, though difficult to verify independently for any specific unit. The practical implication: a correctly seated, OEM-compatible Dyson filter in good condition provides very high-efficiency filtration without bypass. A incorrectly seated or dimensionally mismatched third-party filter in a sealed housing creates a fixed-path bypass leak.
