The T700 DLX is the maximum chemical capture configuration in the 700 T series — 26 lbs of enhanced impregnated activated carbon with a potassium iodide blend, TarBarrier pre-filter, and HepaBarrier post-filter at 635 CFM. Potassium iodide impregnation extends effective adsorption to reactive tobacco smoke compounds — ammonia, hydrogen cyanide, and reactive combustion gases — that standard carbon cannot address efficiently. For the heaviest tobacco smoke environments in larger or higher-volume spaces where both maximum chemical capture range and high airflow are required, the T700 DLX provides the most complete tobacco smoke filtration available at 635 CFM.

TarBarrier Pre-Filter — Dedicated tar compound capture. Protects impregnated carbon service life in heavy smoking environments. Replace based on smoking frequency.
Carbon Bed — 26 lbs Enhanced Impregnated Activated Carbon (Potassium Iodide Blend) — Impregnated with potassium iodide to extend adsorption to reactive smoke compounds: ammonia, hydrogen cyanide, hydrogen sulfide, chlorine compounds, and certain acids. Combined with the full standard adsorption range for tobacco smoke VOCs — benzene, toluene, formaldehyde, and combustion byproducts. The most complete tobacco smoke chemical filtration in the 700 T series.
HepaBarrier Post-Filter — Captures approximately 95% of airborne fine smoke particles at the exit stage.
No pre-packaged replacement bundles for the 700 series. Replacement filters sold individually — contact Fresh Home Air for current filter pricing.

T700 DLX vs. T700: The T700 uses standard activated carbon. The T700 DLX upgrades to enhanced impregnated carbon with potassium iodide — the correct choice when ammonia, HCN, and reactive smoke compounds are the primary concern. T700 DLX vs. T600 DLX: The T600 DLX runs at 560 CFM. The T700 DLX provides 635 CFM — the correct choice when greater airflow is needed for the space volume.

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.
