What to Look for When Buying Buying Guide
1. Performance Specifications
Performance is the cornerstone of any dehumidifier purchase—especially when you’re investing in a 70-pint model. The “70-pint” rating refers to the unit’s moisture removal capacity under standard test conditions (80°F and 60% relative humidity), as defined by the Association of Home Appliance Manufacturers (AHAM). While this number gives you a baseline, real-world performance can vary based on temperature and humidity levels. For example, in cooler basements (below 65°F), refrigerant-based dehumidifiers may struggle with efficiency unless they feature auto-defrost technology.
Look for models that clearly state their AHAM-certified capacity, not just “up to” claims. Also, check the actual water tank size—many 70-pint units have tanks between 1.5 and 2 gallons. If you plan to run the unit continuously without frequent emptying, a larger tank or continuous drainage option is essential. Additionally, pay attention to the unit’s coverage area. A true 70-pint dehumidifier should handle spaces up to 2,500–3,000 sq. ft., but always verify this against your specific room dimensions and humidity level.
2. Built-in Pump Functionality
One of the most important reasons to choose a 70-pint dehumidifier with a pump is the convenience of continuous drainage. Without a pump, you’re limited to gravity drainage, which requires placing the unit higher than the drain point or using a hose that flows downhill. A built-in condensate pump allows you to push water vertically—up to 15 feet or more—and horizontally across long distances, enabling placement in basements, crawl spaces, or utility rooms far from floor drains.
When evaluating pump features, look for specifications like maximum lift height (typically 10–16 feet), pump activation threshold (some start pumping at 50% tank fullness), and whether the pump operates automatically or requires manual engagement. High-quality pumps should be quiet, reliable, and include anti-clog designs. Some premium models even offer dual pumps or backup systems for added reliability. Always ensure the pump is included—not sold separately—as some brands advertise “pump-ready” units that require an additional purchase.
3. Energy Efficiency & Operating Costs
Dehumidifiers are among the most energy-intensive appliances in a home, especially when running 24/7. A 70-pint unit can consume anywhere from 500 to 800 watts per hour, depending on the model and settings. Over time, this adds up—both in electricity bills and environmental impact. That’s why energy efficiency is a critical factor.
Look for models with the ENERGY STAR® certification, which indicates they meet strict efficiency guidelines set by the U.S. Environmental Protection Agency. ENERGY STAR-certified dehumidifiers use 15–20% less energy than standard models. Additionally, check the unit’s Energy Factor (EF), measured in liters of water removed per kilowatt-hour (L/kWh). A higher EF means better efficiency. For example, a model with an EF of 1.8 is more efficient than one with 1.5.
Consider also the unit’s operating modes. Many modern dehumidifiers include “eco” or “energy-saving” modes that adjust fan speed and compressor cycles based on humidity levels. Some even feature programmable timers and humidity sensors that turn the unit on/off automatically, further reducing energy use.
4. Build Quality & Durability
A dehumidifier is a long-term investment, and you want it to last—especially if you’re spending $400 or more. Build quality directly impacts reliability, noise levels, and resistance to wear and tear. Start by examining the materials: look for sturdy, rust-resistant casings (often made from high-impact plastic or coated metal), reinforced coils, and sealed electrical components.
Pay attention to the compressor type. Rotary compressors are generally quieter and more durable than reciprocating ones, though they may cost more. Also, check the quality of the evaporator and condenser coils—copper coils are more efficient and corrosion-resistant than aluminum, though they’re also more expensive.
Another durability factor is the filter. A washable, reusable filter is ideal, as it reduces ongoing costs and maintenance. Some models include antimicrobial filters that inhibit mold and bacteria growth, which is especially useful in damp environments. Avoid units with flimsy plastic parts, weak handles, or poorly sealed tanks—these are red flags for premature failure.
5. Features & Functionality
Modern 70-pint dehumidifiers come packed with features that enhance usability, convenience, and performance. While not all are essential, some can significantly improve your experience. Key features to consider include:
– Humidity Control: Look for digital hygrostats that allow you to set and maintain a specific humidity level (e.g., 45%, 50%, 55%). Auto-humidistats adjust operation based on real-time readings.
– Auto-Defrost: Crucial for cold environments. Prevents ice buildup on coils, ensuring consistent performance in temperatures as low as 41°F.
– Programmable Timer: Lets you schedule start/stop times, ideal for running during off-peak hours or when you’re away.
– Smart Connectivity: Some models offer Wi-Fi or Bluetooth, allowing remote control via smartphone apps. Useful for monitoring humidity levels or receiving alerts when the tank is full.
– Air Filtration: Multi-stage filters (HEPA, activated carbon, or antimicrobial) improve air quality by capturing dust, allergens, and odors.
– Quiet Operation: Measured in decibels (dB), noise levels below 50 dB are considered quiet. Look for insulated cabinets and variable-speed fans.
– Portability: Wheels and handles make moving the unit easier, especially in large homes or multi-room setups.
While feature-rich models offer more control, they may also come with higher price tags. Balance your needs against your budget—don’t pay for smart features if you won’t use them.
6. Brand Reputation & Reliability
Not all brands are created equal. Some have decades of experience in climate control, while others are newer entrants with mixed reviews. Established brands like Frigidaire, GE, and hOmeLabs have strong track records for reliability, customer service, and product innovation. They often invest more in R&D, quality control, and warranty support.
Research brand reputation by reading long-term user reviews, checking ratings on trusted platforms like Consumer Reports or Wirecutter, and looking for recalls or common failure points. For example, some budget brands may use lower-grade compressors that fail after 1–2 years, while premium brands offer 5+ year lifespans with proper maintenance.
Also, consider regional availability. If you live in a rural area, ensure the brand has local service centers or easy return policies. A great dehumidifier is useless if you can’t get it repaired or replaced quickly.
7. Warranty & Support
A solid warranty is a strong indicator of a manufacturer’s confidence in their product. For 70-pint dehumidifiers, look for at least a 1-year full warranty, with some premium brands offering 2–5 years. Pay attention to what’s covered: compressor, pump, electrical components, and labor. Some warranties are voided if the unit is used in commercial settings or without proper maintenance.
Customer support is equally important. Check if the brand offers phone, email, or chat support, and whether they have a responsive service team. Read user reviews about warranty claims—some companies make the process difficult, while others handle it smoothly.
8. Size & Portability
Even though 70-pint dehumidifiers are large appliances, their physical dimensions and weight vary. Most weigh between 40 and 60 pounds and measure roughly 15” x 12” x 24”. However, some models are more compact or have better ergonomics.
Consider where you’ll place the unit. Basements, garages, and crawl spaces often have limited space, so a slimmer profile or vertical design may be preferable. Look for units with recessed handles, smooth-rolling casters, and cord wraps for easy storage and transport.
Also, think about noise and vibration. A heavy, unbalanced unit can vibrate on uneven floors, causing noise and potential damage. Rubber feet or anti-vibration pads help stabilize the unit and reduce sound.
Different Types of Buying Guide
Common Buying Mistakes to Avoid
❌ Mistake: Ignoring Real-World Performance vs. AHAM Ratings
Why it’s bad: Many buyers assume a “70-pint” dehumidifier will remove 70 pints daily in their home. However, AHAM ratings are measured under ideal lab conditions (80°F, 60% RH). In cooler or less humid environments, actual output can drop by 20–40%. Relying solely on the pint rating can lead to underperformance and frustration.
What to do instead: Look for models with strong real-world reviews and consider sizing up if your space is particularly damp or poorly insulated. Some experts recommend choosing a unit rated for 10–20% higher than your needs for optimal performance.
❌ Mistake: Overlooking Pump Specifications
Why it’s bad: Not all pumps are equal. Some have low lift heights (under 10 feet) or weak motors that fail under continuous use. If your drain point is far or elevated, a weak pump won’t suffice, forcing you to manually empty the tank.
What to do instead: Check the pump’s maximum lift and flow rate. Aim for at least 12–15 feet of vertical lift and a pump that activates automatically. Read user reviews to see if others report pump failures or clogs.
❌ Mistake: Skipping Energy Efficiency
Why it’s bad: A cheap dehumidifier may save you $100 upfront but cost hundreds more in electricity over its lifetime. Inefficient models run longer, consume more power, and generate excess heat.
What to do instead: Prioritize ENERGY STAR certification and high Energy Factor ratings. Calculate annual operating costs using the wattage and your local electricity rate. A $50 premium for efficiency can pay for itself in 1–2 years.
❌ Mistake: Buying Based on Price Alone
Why it’s bad: The cheapest 70-pint dehumidifier often uses inferior components, lacks a reliable pump, or has poor customer support. These units may fail within a year, leaving you with repair costs or a replacement.
What to do instead: Focus on value, not just price. Compare features, warranty, brand reputation, and long-term costs. A mid-range model with a 2-year warranty and strong reviews often offers better ROI than a budget option.
❌ Mistake: Ignoring Noise Levels
Why it’s bad: Dehumidifiers can be noisy, especially in living areas or bedrooms. Units above 55 dB can disrupt sleep or conversations. Some models emit a constant hum or rattle when placed on uneven surfaces.
What to do instead: Check decibel ratings and look for insulated cabinets, variable-speed fans, and anti-vibration features. Read user reviews about noise—real-world feedback is more reliable than manufacturer claims.
❌ Mistake: Not Considering Maintenance Needs
Why it’s bad: Dehumidifiers require regular cleaning of filters, coils, and tanks. Neglecting maintenance reduces efficiency, increases energy use, and can lead to mold growth inside the unit.
What to do instead: Choose models with easy-access filters, washable components, and clear maintenance instructions. Set a reminder to clean the unit every 2–4 weeks during peak use.
❌ Mistake: Overlooking Return and Warranty Policies
Why it’s bad: If a unit arrives defective or doesn’t perform as expected, a strict return policy can leave you stuck with a dud. Some retailers charge restocking fees or require you to pay return shipping.
What to do instead: Buy from retailers with generous return windows (30+ days) and free return shipping. Ensure the manufacturer offers a solid warranty and responsive support.
