The manufacturer's own price. You pay what Airpura charges direct, and shipping is free.
Built by Airpura in Montreal, Quebec, in sealed all-metal housings chosen specifically so the machine itself does not off-gas into the air it is cleaning.

What It's Designed For
The C700 DLX is the highest-specification chemical filtration model in the 700 C series — 26 lbs of enhanced impregnated activated carbon at 635 CFM for environments where severe MCS requires both maximum chemical capture range and maximum airflow. Enhanced impregnation extends adsorption to reactive compounds that standard impregnated carbon cannot capture efficiently: ammonia, chlorine-based compounds, hydrogen sulfide, and acid gases. For MCS individuals with wide-spectrum chemical reactivity in larger or higher-volume spaces where the C600 DLX's 560 CFM is insufficient, the C700 DLX provides the same maximum chemical capture profile at 635 CFM.

Filtration System
Pre-Filter — Captures large particles at intake. Protects the carbon bed and post-filter stages. Replace annually.
Carbon Bed — 26 lbs Enhanced Impregnated Activated Carbon — Chemically treated impregnated carbon that extends adsorption range to reactive compounds. Captures the full standard VOC range plus ammonia and nitrogen compounds, chlorine-based compounds, hydrogen sulfide, acid gases, low-concentration formaldehyde, industrial VOCs, and solvents. The 26-lb load at 635 CFM provides correctly calibrated dwell time for effective adsorption. Over 400 specialty blends available for specific chemical environments.
HepaBarrier Post-Filter — Captures approximately 95% of airborne particles at the exit stage. Available in two configurations: HepaBarrier with frame (full assembly) or HepaBarrier filter cloth only for subsequent replacements.
Replacement Filter Bundles

| Filter | Suggested Interval |
|---|---|
| Pre-Filter | Every 12 months |
| Carbon Filter | Every 2 years |
| HEPA Barrier | Every 12 months |
Best For
- MCS individuals with wide-spectrum chemical reactivity including ammonia, chlorine, and reactive gases requiring maximum capture range at the highest available airflow
- Larger or higher-volume spaces where both the C600 DLX's carbon load and greater air exchange rate are needed simultaneously
- Serious chemical sensitivity applications requiring the broadest available adsorption range at 635 CFM
C700 DLX vs. C700: The C700 uses standard impregnated carbon. The C700 DLX upgrades to enhanced impregnated carbon — the correct choice when ammonia, chlorine, or reactive compounds are reactivity triggers. C700 DLX vs. C600 DLX: The C600 DLX runs at 560 CFM. The C700 DLX provides 635 CFM — the correct choice when greater airflow is needed for the space. C700 DLX vs. G700 DLX: The G700 DLX uses enhanced impregnated German-sourced carbon. If carbon manufacturing origin is a reactivity consideration, the G700 DLX is appropriate.

If it is the wrong machine
Run it for 30 days. If it is not right, it costs you nothing.
A purifier is a considered purchase, and you cannot really know until it has been in the room a while. So we made being wrong free. Not a restocking fee, not a return label you pay for — nothing.
What we do
- ✓ No restocking fee
- ✓ We send a prepaid, insured return label
- ✓ Your original shipping refunded too
- ✓ Use it properly first — “normal use is expected and completely fine”
Cost to change your mind: $0.00
What is common in this category
- × Restocking fees, often 15–25% of the purchase
- × Return freight paid by you on a unit this size
- × Original shipping treated as non-refundable
- × Returns refused once the unit has actually been used
Which is the opposite of a trial
Our terms in full: 30-day return policy. Restocking fees are common across the category; we do not charge one.

Frequently asked questions
Everything you need to know before you buy.
Airpura rates this machine for up to 2,500 sq ft at two air changes an hour, with 8-foot ceilings. For four air changes, which is what we suggest for smoke, asthma or chemical sensitivity, plan on about 1,250 sq ft.
Same cabinet, same airflow and the same HEPA Barrier post-filter. The difference is the carbon. The standard model uses activated carbon, which handles most household chemicals, VOCs and odors. The DLX uses impregnated carbon, which Airpura builds for heavier chemical and gas loads. If your concern is everyday VOCs and odors, the C700 costs less ($1,199.98).
Airpura filter life varies by model and usage. Airpura rates the carbon filter at about two years of continuous use in a typical home. 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.
Airpura units use a variable-speed motor, so you dial airflow up or down across a range rather than stepping through fixed settings. At the low end it is quiet enough to sleep beside. At the top of the range it is clearly audible and is meant for clearing a room quickly — after cooking, painting, or on a smoky day — not for running overnight. Most people settle around the middle of the range and leave it there.
No. This unit uses only mechanical filtration — no ionizer, no UV, no ozone generator. That matters for people with asthma or chemical sensitivity, because ozone is a known airway irritant. Airpura does build UV-equipped machines, and they are gathered in the UV air purifiers collection — this is not one of them.
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. Airpura's 600 and 700 series have a variable-speed dial rather than numbered speeds, and a low to medium setting suits continuous use. Continuous operation at a moderate speed outperforms intermittent high-speed runs for maintaining consistent indoor air quality.
