The Airpura C700 is the large-space version of the C600, built to clear chemicals, fumes, and odors from bigger, more open rooms. It carries the same deep bed of activated carbon, but pairs it with a stronger motor that moves more air, so a single unit keeps up with great rooms, open floor plans, and whole levels instead of one closed room.
Like the rest of the C-series, it leads with carbon to adsorb VOCs, gases, and chemical fumes that a particle filter can't touch, then a HEPA-barrier post filter catches carbon dust and particles on the way out. It's a common pick for renovations, chemical sensitivities, and ongoing odor problems in larger homes. Need a smaller room or heavier carbon chemistry? The C600 and C600 DLX are compared below.
How the C700 Compares: C600 vs C600 DLX vs C700
All three are Airpura's chemical and gas abatement units, sharing the same 26 lb carbon load, the same all-metal build, and the same HEPA-barrier post filter. They separate on two things: how strong the carbon chemistry is, and how big a space the motor can handle. The C700 is the large-space option. It keeps the standard carbon but runs a stronger 635 CFM motor for bigger, more open rooms. The C600 DLX instead upgrades the carbon to an impregnated blend while covering the same room size as the C600.

Choose the C700 for larger or open spaces up to about 2,500 sq ft, like a great room, an open floor plan, or a whole level, where its 635 CFM motor keeps the air turning over. The C600 is the better fit for a single room up to about 2,000 sq ft with everyday chemical and odor needs. If your load is heavy or you have chemical sensitivity, the C600 DLX runs an enhanced impregnated carbon (for a smaller room), and the C700's own Super Gas 700 option brings that heavier chemistry to the larger space.
Not sure the C-series is the right line? For everyday odor and allergen control in a large space, the Airpura R700 does the job for less. For wildfire smoke and seasonal VOC spikes, look at the V700. If formaldehyde is your specific concern, the F700 is purpose-built for it.
Coverage is an estimate based on 8-ft ceilings and varies with layout, ceiling height, and pollutant levels.
Is the Airpura C700 Right for You?
The C700 is for larger homes where the air problem is chemical or odor-based, and one small unit can't keep up.
It's an especially strong fit if you:
✔ Need chemical and odor control across a large or open space, not just one room
✔ Are dealing with renovation off-gassing from new paint, flooring, cabinets, or furniture
✔ Notice VOCs or chemical fumes from cleaning products, hobbies, or building materials
✔ Live with chemical sensitivity or fragrance intolerance
✔ Want to clear lingering odors like smoke, cooking, or household chemicals over a wide area
Great fit for:
✔ Great rooms, open floor plans, and whole levels up to about 2,500 sq ft
✔ Large living areas and combined living/dining spaces
✔ Newly renovated or newly furnished larger homes
✔ Offices, studios, and workspaces where chemical products are in use
✔ Homes running continuous low-speed filtration over a big footprint
What the Airpura C700 Removes
Airborne Chemicals, Gases & Odors (Activated Carbon)
The C700's job is the gas side of air quality, the part a HEPA-only unit can't touch. Its 26 lb carbon bed adsorbs a wide range of airborne chemicals and smells:
- Volatile organic compounds (VOCs) from paint, adhesives, flooring, and furniture
- Chemical fumes from cleaning products, solvents, and household materials
- Odors including tobacco smoke, cooking smells, and general household odor
- Named gases such as ammonia, benzene, toluene, hydrogen sulfide, and sulfur dioxide
Airpura carbon blends are made to address over 4,000 named airborne chemicals, which is why the C-series is used well beyond the average home.
Particles (HEPA-Barrier Post Filter)
After air passes through the carbon bed, a HEPA-barrier post filter gives it a final pass on the way out. Its main job is to catch the tiny bits of carbon that naturally shed from the carbon filter as it works, so they don't drift back into the room, along with any dust the prefilter and carbon didn't already stop. The air leaving the unit is clean of both the gases the carbon adsorbed and the particles from filtration itself.
Good to know: the C700 is a carbon-first, chemical-focused unit. If your main concern is allergens and fine particles rather than chemicals, a True HEPA model like the R700 or I700 is the better match.
Key Design Features
26 lb Carbon Bed for Large Spaces
26 lb of activated carbon with about 570 square inches of surface, sized to keep adsorbing chemicals across a bigger footprint rather than one closed room.
High-Capacity 635 CFM Motor
A stronger variable-speed motor delivers up to 635 CFM freeflow (about 450 CFM with filters installed), so the C700 turns over the air in a large space more often than a standard-motor unit.
Pressure-Sealed Filter Chamber
Airpura's pressure seal and felt gaskets force all incoming air through the filters instead of letting it slip around them, so the carbon actually does its work on every pass.
All-Metal Housing
Powder-coated steel with felt (not rubber) gaskets and a separate electrical chamber. No plastic or rubber off-gassing, which matters most in a unit built for chemical sensitivity.
Motor Out of the Airflow
The motor sits outside the clean-air path, so filtered air isn't blown back over it and picking up contaminants on the way out.
Cleanable Prefilter
A washable prefilter catches larger dust before it reaches the carbon, which helps the carbon bed last longer.
Regular or Super Gas? Choosing Your C700 Carbon
Every C700 ships with a 26 lb carbon bed. The choice is how aggressive that carbon needs to be. You just pick the one you need.
Regular C700 (Standard)
- 26 lb activated carbon, 100% coconut shell, made for broad removal of household odors, light chemical exposure, and everyday VOCs across a large space
- Well-suited for cleaning product smells, cooking odors, light smoke, and general off-gassing from furniture and materials
Super Gas 700 (Potassium Iodide Impregnated)
- 26 lb impregnated carbon, a blend of potassium iodide and coconut shell. The potassium iodide speeds up how quickly the carbon binds and removes chemicals
- A better fit for renovation fumes, stronger chemical exposure, urban pollution, or chemical sensitivity (MCS) in a large space where standard carbon may not be enough

Maintenance & Filter Life
The C700 is built for long service intervals with simple upkeep. It has three filters, each on its own schedule:
- Prefilter: vacuum through the grille periodically; replace about every 12 months
- Carbon filter: replace about every 2 years, depending on how heavy your chemical load is
- HEPA-barrier post filter: replace about every 3 to 5 years, depending on use
Running it continuously on low is the simplest way to keep gas and odor control steady across a large space. It draws about 40 watts on low and 120 watts on high, roughly a household light bulb. Keeping indoor humidity around 40% or lower also helps the carbon perform at its best.
Frequently Asked Questions
Should I get the C600, C600 DLX, or C700?
Start with your space and your chemical load. The C600 covers a single room up to about 2,000 sq ft with standard carbon. The C600 DLX fits that same size room but runs an enhanced impregnated carbon for heavier chemical exposure. The C700 keeps standard carbon and adds a stronger 635 CFM motor for larger, more open spaces up to about 2,500 sq ft. For a big space with a heavy chemical load, choose the C700 with its Super Gas 700 carbon.
What's the difference between the C600 and the C700?
Both use the same 26 lb standard carbon and the same all-metal build. The C700 runs a stronger motor: 635 CFM versus the C600's 560 CFM, which is what lets it cover up to about 2,500 sq ft instead of 2,000. If your space is large or open, the C700 keeps up where the C600 would struggle. For a single room, the C600 is the more sensible spend.
How large a space will the C700 cover?
Up to about 2,500 sq ft with standard 8-ft ceilings, which suits great rooms, open floor plans, and whole levels. Coverage depends on layout, ceiling height, and how strong your chemical or odor load is. For ongoing chemical control, running the unit continuously on a lower speed keeps the air turning over steadily rather than only clearing it once.
Does the C700 remove formaldehyde?
The C700's carbon reduces a wide range of VOCs, and formaldehyde-related compounds are among the chemicals its blends can target. If formaldehyde is your main concern, though, Airpura makes a purpose-built line for it: the F700 uses a carbon specifically formulated to capture formaldehyde, which off-gasses slowly and is one of the harder pollutants to hold.
Is the C700 a HEPA air purifier? Will it help with allergies?
The C700 is a carbon-first, chemical and gas unit. It includes a HEPA-barrier post filter that catches carbon dust and particles, but it's not a certified True HEPA allergy purifier. If your priority is pollen, dust, pet dander, and fine particles in a large space, look at a True HEPA model instead, such as the everyday R700 or the allergy-focused I700.
How much are replacement filters, and where do I get them?
Genuine C700 replacement filters are available right here at Pure Indoor Living, starting at $69.98. The prefilter, carbon, and HEPA-barrier replace on different schedules, so you only buy the one that's due rather than a full set each time.
Does the C700 produce ozone?
No. The C700 cleans air by mechanical filtration only: carbon adsorption plus a particle post filter. There's no ionizer and no ozone-generating process, which is exactly what you want in a unit made for chemically sensitive households.
Does the C700 arrive assembled?
Yes. The C700 ships as a single assembled unit on casters, with no tools or assembly required. Unpack it, plug it in, and choose your speed. See the User Manual for setup details.
What does the warranty cover?
The C700 is backed by Airpura's 5-year parts and 10-year labor warranty, which outlasts the first several sets of filters. The unit is also ETL certified to ANSI/UL 507.
Is this a medical device?
No. The Airpura C700 is a residential and commercial air purifier for general indoor air quality. It's not a medical device and isn't intended to diagnose, treat, cure, or prevent any disease or health condition.
