What It's Designed For
The T400 DLX is the heavy-load configuration of the T400 — same compact platform with the carbon stage upgraded to enhanced impregnated activated carbon with a potassium iodide blend. This treatment extends effective adsorption to chemical compounds in tobacco smoke that standard carbon cannot address efficiently, including ammonia, hydrogen cyanide, and reactive smoke compounds that accumulate in environments with heavy or long-term tobacco exposure. The TarBarrier pre-filter remains in the system to protect carbon service life.

Filtration System
TarBarrier Pre-Filter — Removes tar compounds before they reach the carbon bed. Critical for service life in heavy tobacco environments where tar accumulation rapidly fouls unprotected carbon.
Carbon Bed — Enhanced Impregnated Activated Carbon (Potassium Iodide Blend) — Chemically treated impregnated carbon with potassium iodide treatment that extends adsorption to compounds requiring chemical reaction for effective capture: ammonia, hydrogen cyanide, hydrogen sulfide, chlorine compounds, certain acids. Combined with the standard adsorption range for tobacco smoke VOCs — benzene, toluene, formaldehyde, and combustion byproducts.
True HEPA — 99.97% @ 0.3 microns — Captures fine smoke particles, PM2.5, and biological particulate.
Replacement Filter Bundles

Best For
- Heavy or continuous tobacco smoke environments in a single room where the T400's standard carbon is insufficient
- Rooms with accumulated tobacco contamination in building materials (persistent third-hand smoke off-gassing)
- Environments with elevated ammonia or HCN from tobacco combustion requiring impregnated carbon for effective capture
T400 DLX vs. T400: The T400 uses standard activated carbon. The T400 DLX upgrades to enhanced impregnated carbon with potassium iodide treatment — the correct choice for heavy tobacco load or when ammonia and reactive smoke compounds are the primary concern. T400 DLX vs. T600 DLX: The T600 DLX carries 26 lbs of impregnated carbon at 560 CFM for 2,000 sq ft of heavy tobacco coverage. The T400 DLX is correctly sized for single rooms.

Frequently asked questions
Everything you need to know before you buy.
Coverage varies by model — check the product specifications above for the rated room size. As a general rule, all units perform best when running below their rated capacity, which reduces noise and extends filter life.
Airpura filter life varies by model and usage. The carbon bed in this unit is rated to last 2–3 years under continuous use in a typical residential environment. HEPA and pre-filters have their own replacement schedules. Replacement filters are available on our filters page. Running the unit below its rated capacity meaningfully extends filter life.
Austin Air units have 4 speed settings. Speed 1 is quiet enough for sleeping. Speed 2 produces a consistent low hum that most people find unobtrusive. Speed 3 is suitable for daytime use. Speed 4 is intended for rapid air changes in emergency situations — wildfire smoke events, high-pollen days — not for standard overnight operation.
No. This unit uses only mechanical filtration — no ionizer, no UV, no ozone generator. It is safe for people with asthma, chemical sensitivity, and other respiratory conditions where ozone is a known irritant. This is a firm design standard across the entire Austin Air lineup.
Yes. Austin Air and Airpura units are used by patients with asthma, allergies, and chemical sensitivity. The True HEPA captures particle-class triggers and the activated carbon addresses VOCs, odors, and chemical compounds. No ionizer, no ozone — safe for respiratory conditions. For MCS specifically, the HealthMate Plus or Airpura C600 have the most relevant specifications.
Yes. Airpura units are designed for continuous residential operation. The steel-body construction and quality motor components are built for this use case. Most Airpura users run their units continuously at speed 2–3. Continuous operation at a moderate speed outperforms intermittent high-speed runs for maintaining consistent indoor air quality.
Airpura units ship directly from their facility in Montreal, Canada. Orders typically clear customs within 2–3 business days and arrive within 7–14 business days to most US addresses. You will receive a tracking number once your order ships. Import duties and customs fees are included in the product price — no surprise charges at delivery.
Airpura units carry a 5-year warranty on parts and labor. As an authorized Airpura dealer, Fresh Home Air supports the full manufacturer warranty. Contact us at support@freshhomeair.com for warranty service.
We accept returns within 30 days of delivery for units in original condition. Contact us at support@freshhomeair.com to initiate a return. Return shipping is the responsibility of the customer unless the unit arrives damaged or defective. Units that arrive damaged should be reported within 48 hours of delivery with photos.
Yes. No ionizer, no ozone, no UV exposure to room air. The Austin Air HealthMate was specifically studied at Johns Hopkins for use in children's homes — the clinical research involved families with young children. These units are safe for continuous operation in homes with children and pets. They are in fact commonly deployed exactly for this purpose.
