About the Noma 143-1310-6
This guide covers the Noma 143-1310-6, an air purifier for rooms up to 384 sq. ft. on the ENERGY STAR certified list.
Its clean air delivery rate (CADR) is 248 CFM for smoke, 243 CFM for dust, and 254 CFM for pollen, with a PM2.5 CADR of 245 CFM. In a 384 sq. ft. room with an 8 ft ceiling, the smoke CADR works out to about 4.8 air changes per hour.
Air passes through a HEPA-type filter. It also has a timer.
Efficiency is rated at 6.3 CFM of PM2.5 clean air per watt (integrated energy factor). That beats 42% of the 85 Medium Room models in our database. Measured ozone output is 2 ppb.

Safety information
- Plug the purifier directly into a working household outlet. Do not run the cord under rugs or furniture, and do not use a damaged cord or plug.
- Unplug the unit before opening the filter door, changing filters or cleaning it.
- Do not operate the purifier without its filters installed, and use only filters intended for this model.
- Keep the air inlet and outlet clear; never insert objects into the grilles or let children play with the unit.
- Do not use the purifier near water, in a bathroom while showering, or where flammable vapors or aerosols are present.
- An air purifier does not remove carbon monoxide or radon and is not a substitute for ventilation. Keep CO alarms in the home.
Installation and first-time setup
- Remove packaging from the filters
Open the filter door and take every filter out of its plastic bag. Running the purifier with filters still wrapped blocks airflow and can overheat the motor.
- Reinstall filters in order
Fit the filters back in the order and orientation marked on their frames. Most filters have an airflow arrow; it should point toward the fan.
- Choose a location
Place the purifier on a firm, level surface in the room where you spend the most time, with at least a foot or two of clearance from walls, curtains and furniture on the intake and outlet sides.
- Size the space
This model is rated for rooms up to 384 sq. ft. (36 m²) with standard 8 ft ceilings. For higher ceilings, open-plan areas or allergy and smoke concerns, treat a smaller area or add a second unit.
- Power on and reset indicators
Plug in, run the unit on high for a few minutes, and reset the filter-life indicator if the manual asks you to after installing new filters.
| Room area (8 ft ceiling) | Air changes at smoke CADR |
|---|---|
| 385 sq. ft. | 4.8 per hour |
| 290 sq. ft. | 6.4 per hour |
| 190 sq. ft. | 9.8 per hour |
Using your air purifier
Choosing a fan speed
Run the purifier continuously — particles are released all day, and a purifier only cleans the air that passes through it. Use high speed for 20–30 minutes after cooking, cleaning or when smoke is present, then drop to a lower, quieter speed for everyday use. The 248 CFM smoke CADR is measured at the highest speed; lower settings deliver proportionally less clean air.
Using the timer
Use the timer to run the purifier on high before you arrive home or to shut it off after you fall asleep. For continuous cleaning, leave it running at low speed instead of switching it off.
Getting the best results
- Keep doors and windows in the room closed while the purifier runs so it is not trying to clean outdoor air.
- Remove the source where possible: vacuum with a HEPA vacuum, wash bedding weekly and keep pets out of the bedroom if they trigger allergies.
- Position the purifier near where you sit or sleep, with its outlet unobstructed, for the most noticeable benefit.
- Change filters on schedule; a loaded filter reduces CADR and can release odors.
Care and maintenance
| When | What to do |
|---|---|
| Every 2–4 weeks | Vacuum the pre-filter or outer mesh (if fitted) to remove hair and lint, and wipe the intake grille. |
| Every 6–12 months | Replace the main HEPA-type filter when the indicator lights or as the manual specifies. Do not wash or vacuum the pleated media — it damages the fibers. |
| As needed | Wipe the cabinet with a dry or slightly damp cloth. Never spray cleaners into the grilles. |
Troubleshooting
Most air purifier issues relate to filters, placement or the filter-door safety switch. Work through these checks before contacting support. If the display shows a code, consult the code table in your manufacturer's manual.
| Problem | Possible cause | What to try |
|---|---|---|
| Unit will not turn on | Filter door not fully closed (safety switch); outlet not live; child lock on. | Close the filter door firmly; try another outlet; check the manual for unlocking the controls. |
| Weak airflow | Filter still in its bag or overloaded; intake blocked. | Remove packaging, replace or clean filters, and clear space around the intake. |
| Louder than usual | Filter loaded or misaligned; unit on an uneven surface; debris in the fan. | Reseat or replace the filter, move to a level surface, and unplug before checking the fan area. |
| Odor from the unit | Filter has absorbed cooking or smoke odors; new-filter smell. | Replace or clean the filter as the manual directs; run on high in a ventilated room for a few hours if the filter is new. This model has no activated-carbon stage, so it is not designed for odor removal. |
| Filter light stays on | Indicator not reset after replacing the filter. | Follow the manual's reset procedure, usually holding the filter button for several seconds. |
| Air still feels dusty | Room larger than the rating; doors or windows open; purifier on lowest speed. | Compare the room to the 384 sq. ft. rating, close the room, and run a higher speed. |
Energy use and running costs
The Noma 143-1310-6 is rated at 226 kWh per year, an ENERGY STAR estimate that assumes the purifier runs about 16 hours a day and sits in standby the rest of the time. At an average electricity price of $0.17 per kWh, that is about $38.42 per year, or $3.20 a month.
At the high-speed setting used for its CADR test it draws roughly 39 W, so running flat out around the clock would use about 339 kWh a year ($57.62). Everyday operation on a lower speed uses considerably less.
The integrated energy factor of 6.3 CFM/W means every watt delivers about 6.3 cubic feet per minute of PM2.5-free air, including standby losses. Higher numbers mean more clean air for the same electricity.
Replacement filters are usually a larger running cost than electricity, so factor their price and replacement interval into your budget.
Frequently asked questions
What size room is the Noma 143-1310-6 designed for?
It is rated for rooms up to 384 sq. ft. with 8 ft ceilings, which corresponds to about 4.8 air changes per hour at its 248 CFM smoke CADR. For allergies or smoke, use it in a smaller room or run it on high.
What is the CADR of the Noma 143-1310-6?
Its clean air delivery rates are 248 CFM for smoke, 243 CFM for dust, and 254 CFM for pollen, plus a PM2.5 CADR of 245 CFM. Higher CADR means faster cleaning.
Does the Noma 143-1310-6 use a true HEPA filter?
The certification lists the filter as "HEPA-type". HEPA-type is a manufacturer description, not the 99.97%-at-0.3-micron HEPA standard; judge performance by the CADR figures instead.
Does the Noma 143-1310-6 produce ozone?
Its certification test measured 2 ppb of ozone, far below California's 50 ppb limit for indoor air cleaners.
How much electricity does the Noma 143-1310-6 use?
It is rated at 226 kWh per year, about $38.42 at $0.17/kWh, assuming roughly 16 hours of operation a day.
Can I control the Noma 143-1310-6 from my phone?
No. The certified configuration has no app connectivity.
