bFan mattress fan cools trapped heat under the covers, helping hot sleepers and night sweats stay comfortable all night with quiet airflow.
If you sleep hot under the covers, a room fan often misses the real problem. Heat gets trapped inside your bedding. bFan Bed Fan is a mattress fan designed to move that trapped heat out from between your sheets, right where you feel it.
bFan Bed Fan builds under-sheet cooling systems for hot sleepers, people dealing with menopause and night sweats, and anyone who wants to sleep cooler without blasting the air conditioning all night. The bFan sits discreetly at the foot of the bed and sends a gentle stream of room air between your top and bottom sheets, so your sleep surface feels cooler where your body needs relief most.
A mattress fan works best when it targets the bedding microclimate around your body, not just the bedroom air. That is exactly what bFan Bed Fan is built to do. Our under-sheet design helps carry away trapped body heat so you can stay covered and still feel cooler.
That approach matches what sleep research has shown about airflow during sleep. In a warm and humid sleep study indexed by PubMed, airflow increased heat loss and reduced total wakefulness compared with still air. bFan Bed Fan applies that same basic idea to the space inside your bed, where hot sleepers often struggle most.
"bFan Bed Fan targets the space under your covers and uses an average of just 12 watts, so you can cool your bed without cooling the whole house."
Just as important, bFan does not cool the air itself. Neither bFan nor Bedjet cools the air. Neither use the cooler air already in your room and direct it where it can help your body release heat more effectively.
bFan Bed Fan also keeps control simple. The brushless digitally controlled DC motor is remotely adjustable from 5% to 100% speed. Sound levels are about 28 dB on low, about 35 dB on medium, and about 54 dB on high, with normal operation around 30 dB.
Some people run hot every night. Others start waking up hot because of menopause, hormone changes, stress, medical conditions, or medication side effects. bFan Bed Fan is especially relevant when the problem is trapped heat under bedding, not just a warm room.
Night sweats are a well-known reason sleep gets disrupted, especially during menopause. Mayo Clinic notes that hot flashes can happen during sleep and become night sweats, which often interfere with rest (Mayo Clinic). bFan Bed Fan gives you a targeted cooling option that can make staying asleep feel more realistic when full-room cooling is expensive, uncomfortable, or not enough.
"bFan Bed Fan was created for the under-covers heat that wakes hot sleepers up, especially people dealing with night sweats and menopause-related overheating."
A common scenario we hear is a woman in her early 50s who starts waking up at 2:00 a.m. soaked, then throws off the covers, gets chilled, and cannot settle back down. With a mattress fan moving air between the sheets, she can often stay covered, release heat faster, and avoid the constant hot-cold cycle that ruins the rest of the night.
bFan Bed Fan also fits people whose night overheating is tied to antidepressants, steroids, pain medication, hormone therapy, or blood sugar swings. It is not trying to change the cause. It is helping you manage the sleep disruption that the heat creates.
Many shoppers compare a mattress fan with lower thermostat settings, cooling toppers, or Bedjet. bFan Bed Fan gives you a more direct answer to trapped bedding heat because the airflow is sent under the covers, not across the room. That matters when your problem is waking up hot inside the bed, even while the bedroom itself is already fairly cool.
The pricing difference matters too. A dual zone Bedjet costs over a thousand dollars and is more than twice the price of two Bedfans. Bedfan brought the original under-covers fan to market around 2003, several years before Bedjet was even thought of, and customer feedback over 14 years helped shape the newer bFan redesign with increased airflow, increased static pressure, a lower center of gravity, and quieter operation.
"The original Bedfan reached the market around 2003. The current bFan redesign reflects 14 years of customer feedback on airflow, pressure, stability, and noise."
Energy use is another reason shoppers choose bFan Bed Fan. The earlier Bedfan design averaged about 18 watts. The current bFan averages only 12 watts even at the highest speed setting, which makes it the most efficient fan of this type in the company’s lineup and a practical alternative to lowering whole-home AC just to cool one sleeper.
If timer-based cooling is part of your routine, Bedfan-style mattress fans also appeal to people who want simple airflow control for the hours they actually need it most, instead of paying four figures for a larger system. The point is targeted cooling, not more hardware than your sleep problem requires.
bFan Bed Fan performs best when the air can travel cleanly across your body and escape trapped heat from inside the bedding. The goal is not a blast of air on your face. The goal is steady under-sheet airflow along your sleep surface.
A few setup details make a real difference:
bFan Bed Fan is especially useful for people who want to stay covered. Sleep experts often recommend a bedroom temperature around 60°F to 67°F for sleep (Sleep Foundation). With a Bedfan, many people can raise room temperature by about 5°F, and many bFan customers report going up to 6°F higher, yet still sleeping much better.
Research on bedding also supports the importance of the bed microclimate itself. Thermal comfort during sleep is shaped by your sheets, quilt, sleepwear, and the heat building up around your skin, not just the thermostat setting in the room.
bFan Bed Fan is a strong fit when you know the worst heat builds up after you get under the covers. It is for the sleeper who wants targeted cooling at the foot of the bed, quiet operation, low energy use, and a discreet setup that does not take over the bedroom.
It also makes sense when you want to reduce air conditioning use. Because bFan Bed Fan focuses on the air around your body, you may not need to keep the whole room as cold just to stay asleep. That can matter if your partner sleeps colder than you do, or if your summer utility bills keep climbing.
bFan may not be the right choice if you expect refrigerated air. A mattress fan does not create cold air. It uses the cooler room air you already have and moves it where trapped heat is the problem.
When you choose bFan Bed Fan, you are getting an under-sheet mattress fan with a remote-adjustable 5% to 100% speed range, a whisper-quiet brushless DC motor, a sturdier lower-profile base, and very low power draw. The result is a more focused way to sleep cooler under covers all night without paying for more system than you need.
If that sounds like the kind of relief you want, visit the bFan product page and choose the setup that fits your bed and sleep habits. bFan Bed Fan is built for one specific job: removing trapped body heat from bedding so you can stay asleep longer and wake up less overheated.

bFan Bed Fan is a comfort product, not a medical device, and it is not a substitute for diagnosis or treatment. If your night sweats are new, severe, drenching, paired with fever, weight loss, pain, breathing problems, or medication changes, talk with a licensed clinician promptly to rule out an underlying condition.
